Motor Driving Circuit and Correction Method

Abstract

The present invention discloses a motor driving circuit for driving a motor, including an electrostatic discharge diode, having an input port and an output port coupled to a first DC power supply, a pulse width modulation source coupled to the input port of the electrostatic discharge diode to generate a pulse width modulation signal, and a driving module including a voltage detecting module comparing the pulse width modulation signal with a voltage of the output port of the electrostatic discharge diode to generate a voltage comparison result, a lock/restart module generating a shut-down signal according to the voltage comparison result, a control module generating a control signal according to the shut-down signal, and a bridge circuit switching the motor on or off by turning on or turning off an up-bridge circuit and a down-bridge circuit according to the control signal.
