    摘要: An overvoltage protection circuit includes a connection jack, a path connection module, a voltage response module, and a control module. The connection jack is connected to a power supply. The path connection module is connected between the connection jack and a load. The voltage response module is to output a first signal in response to an overvoltage, and output a second signal in response to a constant voltage. The control module is to output a corresponding potential according to the first signal to turn off the path connection module, and output a corresponding potential according to the second signal to turn on the path connection module. When the path connection module is turned off, the connection between the connection jack and the load is disabled, when the path connection module is turned on, the connection between the connection jack and the load is enabled.

    摘要: An electronic device with standby state includes a MCU, a voltage conversion unit, a screen lock circuit, and a power-saving trigger circuit. The voltage conversion unit is connected to the MCU and is used to convert a power supply voltage to a suitable voltage to power the MCU. The screen lock circuit includes a switch, therein, the screen lock circuit is connected to the MCU and is used to lock or unlock the electronic device in response to an operation on the switch when the electronic device is in a work state. The power-saving trigger circuit is connected to the MCU, the voltage conversion unit, and the screen lock circuit, and is used to disable or enable the voltage conversion unit in response to the operation on the switch when the electronic device is in the standby state.
