摘要: A fan system includes a fan, hysteresis circuit including temperature sensor, first operational amplifier having negative input end coupled to the and second an output of positive power supply for outputting voltage when sensed by sensor is greater than temperature, lower temperature. The further switch controlling rotational speed according or outputted from circuit.
