POWER CONTROL CIRCUIT AND POWER CONTROL METHOD

A power control circuit and a power control method are provided. The power control circuit includes a battery unit, a power controller and a switch circuit. The power controller is configured to provide a control signal. The switch circuit is coupled between the battery unit and the power controller. The switch circuit includes a diode component. The diode component is configured to receive the control signal. The switch circuit is configured to cut off a power transmission path of the battery unit in response to a voltage difference between a first terminal and a second terminal of the diode component.
