Monolithic Power Systems (MPS) MPQ6612A H-Bridge DC Motor Drivers include four N-channel power MOSFETs and an internal charge pump that generates gate-drive voltages. These MOSFETs are used to drive reversible motors that drive one DC motor and one winding of a stepper motor. The MPQ6612A drivers with current sense operate on a motor power supply voltage from 4V to 40V and -40°C to 125°C junction temperature range. These drivers are controlled using a Pulse Width Modulation (PWM) input interface. For the MPQ6612A-D-AEC1, control of the outputs is accomplished through the DIR and ENBL pins. For the MPQ6612A-AEC1, control of the outputs is achieved through the IN1 and IN2 pins. Otherwise, both parts are identical.
