A motor driver with low power consumption and wide supply voltage range was designed. By adopting the high efficiency pump circuit and designing new charge pump power supply mode, the motor driver circuit could be implemented to achieve a wide supply voltage range and low power consumption. The driver ensured that the power tube still had a low on resistance and a large output drive current at low voltage, and the power tube gate source will not break down at high voltage. The charge pump clock control circuit was designed, so that the driver had a lower power consumption. This circuit was designed in SMIC 180 nm BCD process. The simulation results show that the motor driver has a motor power input range of 0 V to 15 V, a logic supply range of 1.8 V to 5.5 V, and a quiescent power consumption of 284.5 μA.
