Abstract
A discharge circuit applied in a motherboard includes a platform controller hub (PCH), a first electronic switch, a second electronic switch, and first capacitor. A control terminal of the first electronic switch is coupled to a standby pin of the PCH. A second terminal of the first electronic switch is coupled to the standby power. A control terminal of the second electronic switch is coupled to the second terminal of the first electronic switch. A second terminal of the second electronic switch is coupled to a first power source through a resistor coupled with a capacitor in parallel. The standby pin of the PCH outputs a digital low signal, to control the first electronic switch is turned off rapidly, and the second electronic switch is turned on. A voltage of the first power source is discharged through the resistor rapidly.
