Description
The A2919 motor driver is designed to drive both windings of a bipolar stepper motor or bidirectionally control two DC motors.
Both bridges are capable of sustaining 45 V and include internal pulse width modulation (PWM) control of the output current to 750 mA.
The outputs have been optimized for a low output-s...
