POWER SUPPLY SWITCHING CIRCUIT, ELECTRONIC DEVICE, AND CONTROL METHOD OF POWER SUPPLY SWITCHING CIRCUIT |
| 摘要 |
There is provided a power supply switching circuit including a first control signal output unit that outputs a signal exceeding a predetermined potential using a main power supply as a first control signal when a power supply voltage of the main power supply exceeds a predetermined reference voltage, a second control signal output unit that outputs the signal exceeding the predetermined potential using a standby power supply from a battery as a second control signal when a potential of the first control signal does not exceed the predetermined potential, and a power supply output unit that outputs the main power supply when the first control signal exceeds the predetermined potential and outputs the standby power supply when the second control signal exceeds the predetermined potential |
