摘要： In a fan motor drive circuit which drives a motor based on a pulse-modulated external control signal, a temperature control signal generator generates a pulse-modulated temperature control signal whose duty ratio changes depending on temperature. A signal synthesizer synthesizes the external control signal and the temperature control signal by a logical operation. A drive controller drives the motor based on output of the signal synthesizer.
