The UDN2916B, UDN2916EB, and UDN2916LB motor drivers are 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 saturation
voltage drop (less than 1.
8 V total source plus sink at 500 mA).
For PWM current control, the maximum outp...
