Abstract
The present invention provides a motor driving circuit to reduce switching loss, which is applied to a motor. The motor driving circuit comprises a motor driving unit, a push-pull output unit, and a control unit. The control unit is coupled to the motor driving unit and the push-pull output unit. The control unit transmits a driving voltage to drive the push-pull output unit such that the push-pull output unit generates amplified currents which are transmitted to the motor driving unit. The motor driving unit reduces charge/discharge periods thereof based on the received amplified currents.
