とするモータドライブ回路。In a motor drive circuit including first and second transistors that receive a control signal at their respective bases and output a control voltage to the motor from commonly connected emitters, a connection between the collector of the second transistor and a reference potential point is provided. A third transistor has a collector and an emitter connected in between, and the emitter is connected to the emitter of the second transistor to receive a control signal and turn it on and off together with the second transistor, and the collector is connected to the third transistor. A fourth transistor connected to the base of the motor drive circuit is configured to switch a reference potential point to the collector of the second transistor according to the operation of the third transistor.
