Power supply circuit
A power supply circuit for protecting a battery from current leakage when the battery is not in use includes a control signal input circuit and a switch circuit. The control signal input circuit receives a first control signal from a chip and output a second control signal. The switch circuit receives the second control signal and turns on or off an electronic connection between the battery and the chip. Wherein when the battery is not in use and not being charged by the adaptor, there is a possibility of current leakage from the battery. In such case, the switch circuit turns off the electronic connection between the battery and the chip, and the battery does not provide power to the chip.
