bipolar stepper motor with current control

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).

FEATURES
- 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
- Similar to Dual PBL3717, UC3770
