With reference to
The electronic device 100 may be implemented as various types of electronic devices such as, for example, and without limitation, a TV, a smart phone, a tablet PC, a desktop PC, a laptop PC, an IoT device, or the like.
The power detection IC 110 may detect whether a voltage is abnormal. The voltage may refer, for example, to a voltage used for driving the electronic device 100 and may include a voltage provided to various components included in the electronic device 100. For example, the voltage may include a reference voltage for generating a voltage for driving a display panel of the electronic device 100, a voltage for driving an amplifier for generating sound, a voltage for driving a core inside a main IC and a CPU/GPU, a voltage for DDR communication, a reference voltage for I/O communication, a voltage used for a USB and an internal IP block.
For the above, the power detection IC 110 may include a plurality of input ends. The input ends may be a port into which a voltage is input. For example, the power detection IC 110 may detect whether a voltage applied to each of a plurality of input ends is abnormal. For example, the power detection IC 110 may include three input ends. However, it is merely an example, wherein the number of input ends may be more or fewer than three according to a specification of the power detection IC 110.
That abnormality occurs in a voltage may refer, for example, to there being abnormality in a power source proving a voltage or a magnitude of a voltage is lowered due to other problems.
The power detection IC 110 may output a detection signal. For example, the power detection IC 110 may detect a magnitude of a voltage and output a detection signal corresponding thereto. For example, the power detection IC 110, if it detects that there is no abnormality of the voltage based on the magnitude of the voltage (e.g., if it detects that the voltage is constantly maintained), may output a detection signal having a first level. The first level may be a high level. The power detection IC 110, if it detects that there is abnormality of the voltage based on the magnitude of the voltage (e.g., if it detects that the voltage is lowered), may output a detection signal having a second level. Here, the second level may be a low level. In the aforementioned embodiment, it is described that the first level and the second level are high and low, respectively but it is merely an example, wherein the first and second levels may be low and high, respectively.
The power detection IC 110 may output a system reset signal. For example, the power detection IC 110 may receive a voltage VDD for driving the power detection IC 110. In this case, the power detection IC 110 may detect a magnitude of the voltage VDD for driving the power detection IC 110 and output a system reset signal corresponding thereto. For example, the power detection IC 110, if it detects that there is no abnormality of the relevant voltage based on the magnitude of the voltage VDD for driving the power detection IC 110 (e.g., if the voltage VDD for driving the power detection IC 110 is a preset (e.g., specified) magnitude or more), may output a system reset signal having the first level. The first level may be a high level. The power detection IC 110, if it detects that there is abnormality of the relevant voltage based on the magnitude of the voltage VDD for driving the power detection IC 110 (e.g., if the voltage VDD for driving the power detection IC 110 is less than the preset magnitude), may output a system reset signal having the second level. The second level may be a low level. In the aforementioned embodiment, it is described that the first level and the second level are high and low, respectively but it is merely an example, wherein the first and second levels may be low and high, respectively.
The processor 120 may include various processing circuitry and controls operations of the electronic device 100 overall. For the above, the processor 120 may include a central processing unit (CPU), or the like and may control operations of various hardware included in the processor 150 by executing a software program according to at least one instruction stored in memory (not shown). The processor 120 may include various processing circuitry and/or multiple processors. For example, as used herein, including the claims, the term “processor” may include various processing circuitry, including at least one processor, wherein one or more of at least one processor, individually and/or collectively in a distributed manner, may be configured to perform various functions described herein. As used herein, when “a processor”, “at least one processor”, and “one or more processors” are described as being configured to perform numerous functions, these terms cover situations, for example and without limitation, in which one processor performs some of recited functions and another processor(s) performs other of recited functions, and also situations in which a single processor may perform all recited functions. Additionally, the at least one processor may include a combination of processors performing various of the recited/disclosed functions, e.g., in a distributed manner. At least one processor may execute program instructions to achieve or perform various functions.
For example, the processor 120 may perform an operation corresponding to a level of a detection signal output from the power detection IC 110.
For example, the processor 120, if a level of a detection signal output from the power detection IC 110 is the first level, may identify that there is no abnormality in the voltage.
The processor 120, if a level of a detection signal output from the power detection IC 110 is the second level, may identify that there is abnormality in the voltage. In this case, the processor 120 may output a control signal for turning off a power source providing a voltage to the electronic device 100, thereby turning off the power source. Further, the processor 120 may reset the electronic device 100 and reboot the electronic device 100. Still further, the processor 120 may monitor a level of a detection signal output from the power detection IC 110 in a process of rebooting the electronic device 100.
The processor 120 may perform an operation corresponding to a level of a system reset signal output from the power detection IC 110.
For example, the processor 120, if a level of a system reset signal output from the power detection IC 110 is the first level, may identify that there is no abnormality in the voltage VDD for driving the power detection IC 110. Also, the processor 120, if a level of a system reset signal output from the power detection IC 110 is the second level, may identify that there is abnormality in the voltage VDD for driving the power detection IC 110. In this case, the processor 120 may output a control signal for turning off a power source providing a voltage to the electronic device 100, thereby turning off the power source. Further, the processor 120 may reset the electronic device 100 and reboot the electronic device 100.
According to an embodiment of the disclosure, the power detection IC 110 may detect whether a plurality of voltages are abnormal through one input end, wherein it may be described in greater detail below.
The power detection IC 110 may include an input end 114. The power detection IC 110 may receive a voltage VDD for driving the power detection IC 110 through the input end 114.
The power detection IC 110, if abnormality of at least one voltage of a plurality of voltages is detected, may output a detection signal having a preset level.
A plurality of voltages may include a first voltage and a second voltage.
For example, each of a plurality of input ends 111, 112, 113 of the power detection IC 110 may be connected to a first resistance to which a first voltage is applied. At least one of the plurality of input ends 111, 112, 113 of the power detection IC 110 may be commonly connected to a first resistance to which a first voltage is applied and a switching element connected to a second resistance to which a second voltage is applied.
For example, each of the plurality of input ends 111, 112, 113 may be connected to a first resistance (e.g., resistances R1, R2, R3). For convenience of the description, the resistances connected to the plurality of input ends 111, 112, 113 are referred to as the first resistance in the same name but these are different resistances. Resistance values of these may be identical or different.
The first voltage may be voltages V1, V2, V3 applied to the first resistance connected to each of the plurality of input ends 111, 112, 113. For convenience of the description, the voltages applied to the first resistance are referred to as a first voltage in the same name but these are different types of voltages. For example, different voltages among voltages used for driving the electronic device 100 may be applied to the first resistance.
The first resistance and the switching element may be commonly connected to at least one input end. The switching element may be connected to the second resistance. The second voltage may be applied to the second resistance. For example, the resistance (e.g., R1) and a switching element Tr1 may be commonly connected to the input end 111 and a voltage V4 may be applied to a resistance R4 connected to the switching element Tr1. For convenience of the description, a plurality of resistances connected to a plurality of switching elements are referred to as the second resistance in the same name but these are different resistances. Resistance values of these may be identical or different. For convenience of the description, the voltages applied to the second resistance are referred to as a second voltage in the same name but these are different types of voltages and are different from the first voltage. For example, different voltages among voltages used for driving the electronic device 100 may be applied to the first resistance and the second resistance.
The first voltage is applied to one end of the first resistance. The second voltage is applied to one end of the second resistance. A first end of the switching element is connected to the other end of the second resistance, a second end of the switching element receives a reference voltage, a third end of the switching element is commonly connected to the other end of the first resistance and at least one input end. For example, if the switching element is a BJT, the first end is an emitter, the second end is a base, and the third end is a collector. As another example, if the switching element is MOSFET, the first end is a source, the second end is a gate, and the third end is a drain.
The power detection IC 110 may compare a voltage of at least one input end among the plurality of input ends 111, 112, 113 to a threshold voltage. Further, the power detection IC 110, if a voltage of the plurality of input ends 111, 112, 113 is equal to or greater than the threshold voltage, may output a detection signal having the first level. The power detection IC 110, if a voltage of at least one input end of the plurality of input ends 111, 112, 113 is less than a threshold voltage, may output a detection signal having the second level.
A method in that the power detection IC 110 detects abnormality of a voltage and outputs a detection signal corresponding thereto is described in greater detail below.
For example, the power detection IC 110, if a first voltage is lower than a threshold voltage, may output a detection signal having a preset level. The preset level may be the second level.
According to an embodiment of the disclosure, a magnitude of a reference voltage applied to the switching element may be set in consideration of a magnitude of a voltage applied to a resistance connected to the switching element. For example, the magnitude of the reference voltage may be the same as the magnitude of the voltage applied to the resistance. Accordingly, if the magnitude of the voltage applied to the resistance is not lowered but is maintained, there is no difference of voltages between the second end and the first end of the switching element, wherein the switching element may be in an off state.
For example, if the switching element Tr1 is in the off state, it may be considered that only the resistance R1 is connected to the input end 111. Meanwhile, the resistances R2, R3 are connected to the input ends 112, 113.
In this case, the voltages V1, V2, V3 applied to the resistances R1, R2, R3 may be applied by an internal design of the power detection IC 110 to the input ends 111, 112, 113, respectively. Accordingly, the power detection IC 110 may compare the voltages V1, V2, V3 of the plurality of input ends 111, 112, 113 to detect whether the voltages V1, V2, V3 are smaller than a threshold voltage. Here, the threshold voltage may be a voltage preset in the power detection IC 110.
Further, the power detection IC 110, if the voltages V1, V2, V3 of the plurality of input ends 111, 112, 113 are is equal to or greater than the threshold voltage, may output a detection signal having the first level. The power detection IC 110, if at least one voltage of the voltages V1, V2, V3 of the plurality of input ends 111, 112, 113 is less than a threshold voltage, may output a detection signal having the second level.
If the switching element is turned on based on the second voltage and a reference voltage applied to the switching element, the power detection IC 110 may compare the second voltage applied to the at least one input end to a threshold voltage to detect whether the second voltage is abnormal.
For example, if the second voltage is less than the reference voltage, the switching element may be turned on. In this case, the power detection IC 110, if a second voltage is lower than a threshold voltage, may output a detection signal having a preset level. The preset level may be the second level.
For example, if there is abnormality in the voltage applied to a resistance connected to the switching element and a magnitude of the voltage becomes smaller, a magnitude of the voltage of the first end of the switching element becomes smaller and thus, a difference of voltages of the first end and the second end of the switching element occurs. Further, if the difference of voltages becomes greater than the threshold voltage of the switching element, the switching element may be turned on. Accordingly, the first resistance and the second resistance may be commonly connected to the input end.
For example, if a magnitude of the voltage V4 becomes lower, the switching element Tr1 may be turned on and the resistance R1 and the resistance R4 may be commonly connected to the input end 111.
In this case, a relatively small voltage among the voltage V1 applied to the resistance R1 and the voltage V4 applied to the resistance R4 may be applied by an internal design of the power detection IC 110 to the input end 111. It may be that a voltage lower than the voltage applied to the first resistance is applied to the second resistance. For example, a voltage of a relatively small magnitude among voltages used for driving the electronic device 100 may be applied to the second resistance.
Accordingly, the voltage V4 is applied to the input end 111, wherein the power detection IC 110 may compare the voltage V4 of the input end 111 to the threshold voltage to detect whether the voltage V4 is less than the threshold voltage. The threshold voltage may be a voltage preset in the power detection IC 110.
The power detection IC 110, if the voltage V4 of the input end 111 is the threshold voltage or more, may output a detection signal having the first level. The power detection IC 110, if the voltage V4 of the input end 111 is less than the threshold voltage, may output a detection signal having the second level. The switching element is not connected to the input ends 112, 113. In this case, the power detection IC 110 may compare the voltages V2, V3 of the input ends 112, 113 to detect whether there is abnormality in the voltages V2, V3.
As above, according to an embodiment of the disclosure, whether there is abnormality with respect to one or more voltages per input end may be detected by adding an additional circuit (e.g., a switching element and a resistance) to the input end of the power detection IC 110. Accordingly, whether the additional voltage is abnormal may be detected without increasing the number of the detection circuit ICs, thereby reducing costs.
For example, it is assumed that the reference voltage V1 (=13 V) for generating a voltage to drive a display panel is applied to the resistance R1, the voltage V2 (=18 V) for driving the amplifier to generate sound is applied to the resistance R2, the voltage V3 (=5 V) used in a USB is applied to the resistance R3, and the reference voltage V4 (=3.3 V) for I/O communication is applied to the resistance R4. Further, it is assumed that the threshold voltage set in the power detection IC 110 is 4 V.
The reference voltage for generating a voltage to drive the display panel and the voltage for driving the amplifier to generate sound have a relatively large voltage value compared to the threshold voltage. In this case, the relevant voltages are distributed by a voltage distribution circuit (not shown), respectively and a voltage of 5 V may applied to the resistance R1 and the resistance R2.
In this case, the power detection IC 110, if at least one of a voltage applied to the resistance R1, a voltage applied to the resistance R2, or a voltage applied to the resistance R3 is smaller than the threshold voltage, may output a detection signal having the second level. If the threshold voltage of the switching element Tr1 is 0.7 V and the voltage applied to the resistance R4 is lowered to 3.3 V, the switching element Tr1 is turned on and 3.3 V may be applied to the input end 111. Accordingly, the power detection IC 110, if the voltage of the input end 111 is smaller than the threshold voltage, may output a detection signal having the second level.
It is shown in
For example, each of a plurality of input ends may be commonly connected to the first resistance to which the first voltage is applied and a switching element connected to the second resistance to which the second voltage is applied. If the switching element is turned on based on the second voltage and a reference voltage applied to the switching element, the power detection IC 100 may compare the second voltage applied to the plurality of input ends to a threshold voltage to detect whether the second voltage is abnormal.
For example, as shown in
In this case, the power detection IC 110, if a magnitude of the voltages V4, V5, V6 becomes lower and the switching elements Tr1, Tr2, Tr3 are turned on, may compare the voltages V4, V5, V6 applied to the plurality of input ends 111, 112, 113 to the threshold voltage to detect whether the voltages V4, V5, V6 are abnormal.
It is described in the aforementioned embodiments that one switching element is connected to the input end but it is merely an example. That is, according to an embodiment of the disclosure, a plurality of switching elements may be connected to the input end and the second resistance to which the second voltage is applied may be connected to each switching element.
For example, as shown in
In this case, the power detection IC 110, if a magnitude of the voltage V4 becomes less and the switching element Tr1 is turned on, may compare the voltage V4 applied to the input end 111 to the threshold voltage to detect whether the voltage V4 is abnormal. The power detection IC 110, if a magnitude of the voltage V7 becomes smaller and the switching element Tr4 is turned on, may compare the voltage V7 applied to the input end 111 to the threshold voltage to detect whether the voltage V7 is abnormal.
It is shown in
