Abstract
A circuit includes an ATX power connector with a PSON pin, a time delay circuit, and a stabilizer circuit. The time delay circuit receives an input PSON# signal and then sends an output PSON# signal to the PSON pin of the power connector after a time delay has elapsed. The stabilizer circuit is coupled to the PSON pin of the power connector for stabilizing the output PSON# signal.
Claims14
A circuit comprising:
- an ATX power supply connector mounted on a motherboard and connected to an ATX power supply, the ATX power supply connector having a Power Supply On (PSON) pin;
- a Super I/O chip mounted on the motherboard capable of sending a PSON# signal to the PSON pin of the power supply connector to power on or off the ATX power supply;
- and
- a time delay circuit connected between the Super I/O chip and the power supply connector, the time delay circuit has an input terminal capable of receiving the PSON# signal from the Super I/O, and an output terminal capable of sending a delayed PSON# signal to the PSON pin of the power supply after a time delay has elapsed.
