Abstract
Disclosed is a motor driving circuit of an EPB system which may reduce dark current. The present invention provides a motor driving circuit, including: a motor which includes two power input terminals to be applied with a battery power and a ground power; an H-bridge circuit which alternatively applies the battery power and the ground power to the two power input terminals in response to four motor driving signals applied from an ECU to drive the motor; an activating transistor which is connected between the battery power and the H-bridge circuit and is activated in response to a fail-safe control signal applied from the ECT to apply the battery power to the H-bridge circuit; and two monitoring units which are connected to corresponding input terminals of two power input terminals of the motor to distribute a voltage level which is applied to the motor and output monitoring signals.
