Additional Information
PWM Motor Driver ICsDual Full-Bridge
The UDx2916 motor drivers control two DC motors bidirectionally as well as working both windings of a bipolar stepper motor. Both bridges have the ability to support 45 V and have 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:
- Internal clamp diodes
- Internal PWM current control
- Low output saturation voltage
- Internal thermal shutdown circuitry
