Lock protection and standby mode control circuit of motor driving apparatus
A motor driving apparatus including a lock protection unit, a standby mode control unit, and a motor control circuit is provided. The lock protection unit receives a motor speed signal representing the rotation of the motor and generates a lock signal accordingly. The standby mode control unit receives a PWM signal and the lock signal and generates a standby mode control signal accordingly. The lock protection unit decides whether to stop generating the lock signal or not accordingly to the standby mode control signal. The motor control circuit controls the rotation of the motor according to the PWM signal and changes the operation mode according to the standby mode control signal and the lock signal.
