A power switch circuit includes a voltage selecting circuit, an auxiliary transistor and a control circuit. The control circuit includes an inverter, or a first inverter and a second inverter forming a latch. The power switch circuit is capable of tracing a higher supply voltage and outputting the voltage level of the higher supply voltage without a voltage drop, so the junction leakage can be eliminated and the drive capability of the power switch circuit is ensured. |
