Product Summary

The UDN2916BT is a dual full-bridge PWM motor driver. The UDN2916BT 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 UDN2916BT outputs have been optimized for a low output saturation voltage drop (less than 1.8 V total source plus sink at 500 mA).
