POWER SUPPLY CONTROL CIRCUIT AND METHOD |
摘要 |
A power supply control circuit for a motherboard of a computer is provided. The power supply control circuit includes a south bridge chip and a voltage output control circuit connected to the south bridge chip. The south bridge chip includes a control pin and a detecting pin. The voltage output control circuit has a voltage input terminal and a voltage output terminal. The voltage output control circuit includes a transistor connected to the voltage input terminal and also connected to the voltage output terminal via a switch component. The voltage output terminal is connected to the detecting pin of the south bridge chip via a super I/O chip. The transistor is capable of controlling the switch component to transmit a high level voltage to the super I/O chip when the computer is shut down. A method is also provided.
