According to an embodiment, the first interface 210 may include a socket electrically connected to the first external electronic device 110. For example, the first interface 210 may include a socket; when the plug of the first external electronic device 110 is electrically connected to the socket, the first interface 210 may receive power (e.g., 5 V) from the first external electronic device 110 through a socket. For example, the socket may be a socket of USB type-C standard. Alternatively, the first interface 210 may include a plug and may be electrically connected to the socket of the first external electronic device 110.
According to an embodiment, the second interface 220 may include a plug electrically connected to the second external electronic device 120. For example, the second interface 220 may include a plug; when the plug is electrically connected to the socket of the second external electronic device 120, the electronic device 200 may transmit and receive at least one of data or power with the second external electronic device 120. The plug may be a plug of USB type-C standard. The data may include control data and output data (e.g., image data). The plug may be electrically connected to the first end of the cable extending to the outside of the electronic device 200; the second end of the cable may be connected to the printed circuit board of the electronic device 200. Alternatively, the second interface 220 may include a socket and may be electrically connected to the plug of the second external electronic device 120.
According to an embodiment, the input device 230 may generate a first signal associated with the disconnection of the first external electronic device 110. For example, when the input device 230 enters the first state depending on the input of the external object, the input device 230 may release the first external electronic device 110 from being mechanically locked to the first interface. The input device 230 may output a first signal in the first state. For another example, when the input device 230 enters the second state depending on another input of the external object, the input device 230 may mechanically lock the first external electronic device 110 to the first interface 210. The input device 230 may output a second signal in the second state. For example, the input device 230 may include a push button switch or a tap switch in which a state (the first state or the second state) is switched depending on the input by an external object. For example, the input device 230 may be formed to be in a first state when being pressed by an external object (a user); and, the input device 230 may be formed to be in a second state when not pressed by an external object. It will be described later that the input device 230 mechanically locks the first external electronic device 110 or releases the mechanical lock to the first external electronic device 110, with reference to
According to an embodiment, the switch 250 is provided between the first interface 210 and the second interface 220, and may be opened or shorted under the control of the processor 240. The switch 250 may deliver at least part of power received from the first external electronic device 110 to the second external electronic device 120 through the second interface 220 at the short-circuit time. The rest of the power received from the first external electronic device 110 may be used as the driving power of the electronic device 130. For example, the switch 250 may include a load switch.
According to an embodiment, the protection circuit 260 may be provided on a path for receiving power from the first external electronic device 110 via the first interface 210. When the voltage received through the first interface 210 is not less than a threshold magnitude, the protection circuit 260 may cut off the output of the received power. Furthermore, when the voltage received through the first interface 210 is less than the threshold magnitude, the protection circuit 260 may output (e.g., bypass) the received power. For example, the protection circuit 260 may include an over-voltage protection circuit.
According to an embodiment, the power selection circuit 270 may receive power through at least one of the first interface 210 or the second interface 220 and may output one of the received powers as the driving power of the components of the electronic device 200. For example, when receiving power through the first interface 210 or the second interface 220, the power selection circuit 270 may output the received single power. For another example, when the power selection circuit 270 receives the power from both the first interface 210 (being received from the first external electronic device 110) and the second interface 220 (e.g., being received from the second external electronic device 120), the power selection circuit 270 may selectively output relatively high power among the two received powers (e.g., being supplied to the processor 240).
According to an embodiment, the power selection circuit 270 may include a comparator, a first switch, and a second switch. The comparator may compare the magnitude of the voltage from the first external electronic device 110 with the magnitude of the voltage from the second external electronic device 120. The first switch 250 may be provided on a path through which power is supplied from the first external electronic device 110; when the power from the first external electronic device 110 is greater than the power from the second external electronic device 120, the first switch 250 may be shorted; otherwise, the first switch 250 may be opened. The second switch may be provided on a path through which power is supplied from the second external electronic device 120; when the power from the second external electronic device 120 is greater than the power from the first external electronic device 110, the second switch may be shorted; otherwise, the second switch may be opened. The output power of the power selection circuit 270 may be used as the driving power of components of the electronic device 200 including the processor 240.
According to an embodiment, the power delivery (PD) controller 280 may communicate with the second external electronic device 120 depending on the command of the processor 240 (e.g., USB Type-C communication) and then may transmit data associated with a first power switch request or data associated with a second power switch request to the second external electronic device 120. For example, the data associated with the first power switch request may include a request (a power role swap request) that allows the second external electronic device 120 to output power. When receiving the data associated with the first power switch request, the second external electronic device 120 may operate as a power supply device (source) in response to the received data, and the electronic device 200 may operate as a power reception device (sink). For example, the data associated with the second power switch request may include a request of cutting off the power output of the second external electronic device 120. When receiving the data associated with the second power switch request, the second external electronic device 120 may operate as a power reception device (sink) in response to the received data, and the electronic device 200 may operate as a power supply device (source).
The PD controller 280 may convert a data transmission/reception standard received from the second external electronic device 120 through the second interface 220 depending on the command of the processor 240. For example, the data transmission/reception standard may include a display port, a high definition multimedia interface (HDMI), a video graphics array (VGA), or the like.
According to an embodiment, the output device 290 may output data received from the second external electronic device 120 through the second interface 220 depending on the command of the processor 240. For example, the received data may include at least one of audio data or image data (e.g., video data). The output device 290 may include at least one of a sound output device (e.g., a speaker, a headphone, an earphone, or the like) outputting audio data or a display outputting video data.
The processor 240 may perform data processing or an operation associated with a control and/or a communication of at least one other component(s) of the electronic device 200 by using the instructions stored in the memory (not illustrated). For example, the processor 240 may include at least one a central processing unit (CPU), a graphic processing unit (GPU), a microprocessor, an application processor (AP), and an application specific integrated circuit (ASIC), a field programmable gate arrays (FPGA) and may have a plurality of cores.
According to an embodiment, when receiving data (image data) from the second external electronic device 120, the processor 240 may output the received data through the output device 290. For example, in a state where the first external electronic device 110 is not connected to the first interface 210, and the second external electronic device 120 is connected to the second interface 220, the processor 240 may receive power and data (image data) from the second external electronic device 120 through the second interface 220 and may output the received data through the output device 290 while operating using the received power.
According to an embodiment, when the first external electronic device 110 is connected, the processor 240 may receive power from the first external electronic device 110 and then may deliver the received power to the second external electronic device 120. For example, in a state where the second external electronic device 120 is connected to the second interface 220, when identifying that the first external electronic device 110 is connected to the first interface 210, the processor 240 may transmit data associated with a second power switch request to the second external electronic device 120. For example, the data associated with the second power switch request may include a request that allows the second external electronic device 120 to cut off the power output. For another example, the data associated with the second power switch request may include a request that allows the second external electronic device 120 to operate as a power reception device (sink). The processor 240 may identify that the first external electronic device 110 is connected to the first interface 210, depending on detecting whether power is received from the first external electronic device 110.
When identifying that the first external electronic device 110 is connected to the first interface 210, the processor 240 may short the switch 250. As the switch 250 is shorted, at least part of the power received from the first external electronic device 110 may be delivered to the second external electronic device 120 through the switch 250. For example, the processor 240 may short the switch 250 at the time of transmitting the data associated with the second power switch request to the second external electronic device 120. For another example, the processor 240 may transmit a second power switch request to the second external electronic device 120 and may short the switch 250 after waiting until the power from the second external electronic device 120 is cut off. According to the above-described embodiment, the processor 240 may prevent the two received powers from colliding with each other as power is received from both the first external electronic device 110 and the second external electronic device 120.
According to an embodiment, while the processor 240 operates using power from the first external electronic device 110, when identifying a disconnection notice (e.g., a first signal) of the first external electronic device 110, the processor 240 may request the second external electronic device 120 to supply power. For example, the first signal may be a signal output to provide a notification that the input device 230 is switched to the first state depending on the input of the external object. The first state may be a state in which the input device 230 releases the first external electronic device 110 from being mechanically locked to the first interface 210 (or a state in which the first external electronic device 110 is mechanically detached from the input device 230). For example, while receiving power from the first external electronic device 110 connected to the first interface 210, when the processor 240 receives the first signal from the input device 230, the processor 240 may be configured to receive power from the second external electronic device 120 through the second interface 220 (e.g., changing settings associated with the second interface between the electronic device and the second external electronic device). For another example, while receiving power from the first external electronic device 110 connected to the first interface 210, when the processor 240 receives the first signal from the input device 230, the processor 240 may transmit data associated with the first power switch request to the second external electronic device 120 through the second interface 220 and may receive power from the second external electronic device 120 in response to the first power switch request. According to the above-described embodiment, before the first external electronic device 110 is electrically disconnected from the first interface 210, the processor 240 may receive power from the second external electronic device 120; accordingly, as the power is temporarily cut off while the power supply source is being replaced, the problem that the electronic device 200 is temporarily turned off and initialized may be prevented.
The processor 240 may transmit data associated with the first power switch request and may open the switch 250. For example, the processor 240 may open the switch 250 at the time of transmitting data associated with the first power switch request. For another example, the processor 240 may transmit the first power switch request, and then may open the switch 250 after waiting until the power is supplied from the second external electronic device 120. According to the above-described embodiment, the processor 240 may prevent the two powers from colliding with each other as power is received from both the first external electronic device 110 and the second external electronic device 120.
According to an embodiment, while receiving power from both the first external electronic device 110 and the second external electronic device 120, the processor 240 may request the second external electronic device 120 to stop supplying power. For another example, while receiving power from both the first external electronic device 110 and the second external electronic device 120, when the processor 240 receives the second signal from the input device 230, the processor 240 may transmit data associated with the second power switch request to the second external electronic device 120 through the second interface 220. The second external electronic device 120 may stop outputting power through the second interface 220 in response to the second power switch request. When the processor 240 receives the second signal, the processor 240 may short the switch 250 and may deliver at least part of power from the first external electronic device 110 to the second external electronic device 120 via the switch 250. According to the above-described embodiment, in the first state of the input device 230, when the first external electronic device 110 is not electrically disconnected from the electronic device 200, the processor 240 may prevent a collision between the power of the first external electronic device 110 and the power of the second external electronic device 120 upon cutting off the power from the second external electronic device 120.
According to an embodiment, when the first external electronic device 110 is disconnected from the first interface 210 after the processor 240 receives the first signal, the processor 240 may receive power from the second external electronic device 120 through the second interface 220 and operate using the received power. When identifying that power from the first external electronic device 110 is not received, the processor 240 may identify that the first external electronic device 110 is disconnected from the first interface 210. In the first interface 210, the electronic device 200 may operate as a power reception device (sink), and the second external electronic device 120 may operate as a power supply device (source).
According to an embodiment, the input device 230 may include a grip sensor, which is positioned to detect a grip on at least part of the first interface 210 by an external object, instead of the mechanical fixation described above. To connect to the first external electronic device 110 to the first interface 210, when an external object grips at least part of the first interface 210, the grip sensor may output a first signal; when the external object does not grip the first interface 210, the grip sensor may output a second signal. When the processor 240 receives the first signal, the processor 240 may transmit data associated with the first power switch request to the second external electronic device 120 and may short the switch 250. On the other hand, when the processor 240 receives the second signal, the processor 240 may transmit data associated with the second power switch request to the second external electronic device 120 and may open the switch 250.
According to an embodiment, the input device 230 may include a touch sensor, which is positioned to detect a touch to at least part of the first interface 210. To connect to the first external electronic device 110 to the first interface 210, when an external object touches at least part of the first interface 210, the touch sensor may output a first signal; when the external object does not touch the first interface 210, the touch sensor may output a second signal. When the processor 240 receives the first signal, the processor 240 may transmit data associated with the first power switch request to the second external electronic device 120 and may short the switch 250. On the other hand, when the processor 240 receives the second signal, the processor 240 may transmit data associated with the second power switch request to the second external electronic device 120 and may open the switch 250.
According to the above-described embodiment, when the electronic device 130 detects that the first external electronic device 110 is disconnected from the first interface 210, the electronic device 130 may quickly switch the second external electronic device 120 from a power reception device to a power supply device; accordingly, before the first external electronic device 110 is electrically disconnected from the electronic device 130, the electronic device 130 may receive driving power from the second external electronic device 120. As such, the electronic device 130 may prevent the reset of the electronic device 200 due to the temporary interruption of a power supply in the process of replacing the power supply.

According to an embodiment, the input device 230 may include a button 231 and the locking member 232.
For example, the button 231 may be switched to a first state (e.g., a pressed state) or a second state (e.g., a protruding state) depending on the input of the external object; the button 231 may operate in conjunction with a peripheral circuit (e.g., a pull-up or pull down circuit) to output a first signal (e.g., a high signal) in the first state and to output a second signal (e.g., a low signal) in the second state. For example, while the button 231 is pressed by an external object, the button 231 may remain in the first state; when the button 231 is not pressed by an external object, the button 231 may be switched to the second state.
As at least part of the locking member 232 is inserted into the interior of the housing 200H in the first state (e.g., the pressed state) of the button 231, at least part of the locking member 232 may release the plug 131 of the first external electronic device 110 from being mechanically locked to the first interface 210. In this case, the plug 131 of the first external electronic device 110 may be separated from the first interface 210. As the locking member 232 is formed to protrude in the second state of the button 231 and holds the plug 131 of the first external electronic device 110 not to be separated from the coupling hole 200G, the locking member 232 may mechanically lock the plug 131 of the first external electronic device 110 to the first interface 210.
The input device 230 may further include an elastic member (not illustrated) (e.g., a spring) interposed between the button 231 and the locking member 232. The elastic member (not illustrated) may insert at least part of the locking member 232 into the housing 200H by applying a force to pull the locking member 232 toward the interior of the housing 200H in the first state of the button 231. On the other hand, the elastic member (not illustrated) may support at least part of the locking member 232 to protrude outside the housing 200H as the locking member 232 is not pulled in the second state of the button 231. The coupling structure of the button 231, the locking member 232, and the elastic member (not illustrated) may be easily derived by those skilled in the art, and detailed description thereof will be omitted.
