Abstract:
A motor driving integrated circuit comprising: a speed control circuit configured to control a rotation speed of a motor according to a speed control signal; a detecting circuit configured to detect whether the speed control signal indicates stop of rotation of the motor; and a shut-off circuit configured to shut off power supply to a circuit included in the motor driving integrated circuit when the detecting circuit detects that the speed control signal indicates stop of rotation of the motor.
