Abstract:
A fan control circuit includes an integrated circuit (IC), a thermistor, and a transistor. A first input of the IC is connected to a fan power supply. A second input of the IC is connected to a stand-by power supply. A base of the transistor is grounded through the thermistor. An emitter of the transistor is connected to an output of the IC. A collector of the transistor is connected to a fan.
