Abstract:
1. A power control circuit applies to transfer a output signal of a chipset for use in a power interface controller, said chipset outputs a STR(Suspend to RAM) control signal and a power supply signal, said power control circuit comprising: a first inverter inverts said STR control signal and output a inverted STR control signal; a second inverter inverts said power control signal and output a inverted power control signal; an AND gate is coupled to said second inverter and outputs a first interface signal according to said STR control signal and said inverted power control signal, and an OR gate is coupled to output terminals of said first inverter and said second inverter and outputs a second interface signal according to said inverted STR control signal and said inverted power control signal; Wherein said power interface controller adjusts a power supply state of a host system according to said first interface signal and said second interface signal.
