Description

The A4970 motor driver drives both windings of a bipolar stepper motor or bidirectionally controls 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.

Features and Benefits

▪ 750 mA continuous output current

▪ 45 V output sustaining voltage

▪ Internal clamp diodes

▪ Internal PWM current control

▪ Low output saturation voltage

▪ Internal thermal shutdown circuitry

▪ Pin compatible with UDx2916

▪ DMOS outputs
