Abstract

A drive circuit drives a motor in a mode selected from first and second modes. A drive unit operates in response to a control signal received from a signal generation unit to control how the motor should rotate. The control signal is applied to drive the motor in the first mode. The signal generation unit receives a select signal indicating one of the first and second modes. When the select signal indicates the first mode, the signal generation unit outputs an input signal as the control signal. When the select signal indicates the second mode, the signal generation unit generates the control signal in accordance with the input signal. A motor drive circuit capable of driving a motor regardless of a difference between input modes in type, and electronics equipped with, can thus be obtained.
