MTS2916A-HGC1

The MTS2916A-HGC1 is a dual CMOS full-bridge Motor Driver capable of driving both windings of a bipolar stepper motor or bidirectional control two DC motors. Each of the two independent H-bridge outputs is capable of sustaining 40V and delivering up to 750mA of continuous current. The output current level is controlled by an internal pulse-width modulation (PWM) circuit that is configured using two logic inputs, a current sense resistor and a selectable reference voltage. The H-bridge outputs optimized to provide a low output saturation voltage drop. Full, half and micro-stepping operations are possible with the PWM current control and logic inputs. The maximum output current is set by a sensing resistor and an user selectable reference voltage. The output current limit is selected using two logic level inputs.
