A driver circuit of a hydraulic pump motor of an anti-lock brake system and a driving method of the same are provided to remove the noise of the hydraulic pump motor at a low speed zone. A driver circuit of a hydraulic pump motor of an anti-lock brake system comprises: a hydraulic pump motor(116) returning the brake fluid accumulated in an accumulator to a mess cylinder; a microcontroller(115) controlling the hydraulic pump motor; a control signal generator(130) transmitting a control signal to the microcontroller; a sub power relay(120) in which the control signal generator is driven; and an ignition signal sensor(125) in which the microcontroller is driven by sensing the on or off status of an ignition switch. |
