ABSTRACT:
A semiconductor device included in a motor driving apparatus for driving a motor is disclosed. The semiconductor device configured to control rotation of the motor by changing the gain of a control loop of the motor driving apparatus. The semiconductor apparatus includes plural gain maintaining parts, each gain maintaining part maintaining at least one gain, and a gain switching part for switching the gains maintained in the gain maintaining parts according to a rotational frequency of the motor.
