Abstract
A motor driving apparatus is disclosed herein and includes a control unit, a soft-start unit and an output unit. When power-up or lock release situation, an external PWM driving signal is inputted to the soft-start unit, the soft-start unit generates an internal PWM driving signal and a power-up initial signal; after the power-up initial signal is generated, the control unit transmitting a motor rotation signal to the soft-start unit; when the soft-start unit counts a plurality of the motor rotation signal, the soft-start unit selects the external PWM driving signal or the internal PWM driving signal to output to the output unit.
