Abstract
A power switch circuit is disclosed. The power switch circuit includes a switch circuit, a first current protection circuit, a second current protection circuit and a selection circuit. The switch circuit is coupled between an input terminal and an output terminal. The switch circuit includes a first sensing switch, a second sensing switch and a power switch. The first sensing switch, the second sensing switch and the power switch are the same cell. The first current protection circuit is coupled to the second sensing switch. The second current protection circuit is coupled to the first sensing switch. The selection circuit is coupled to the switch circuit, first current protection circuit and second current protection circuit. The selection circuit generates a selection signal according to an output voltage to selectively enable the first current protection circuit or second current protection circuit.
