DC motor driver IC from Allegro has typical input voltage range of 3 to 5.5V

Logic input pins are provided to control the motor rotation, brake, and standby (at less than 500 nA supply current) to allow optional pulse-width modulation of the sink drivers. Internal circuitry includes thermal shutdown, undervoltage lockout and crossover current (shoot-through) protection.

Typical applications include robotic actuators and pumps, portable printers and scanners, camera lens and shutter controls, battery powered toys and games, and low-noise test instrumentation systems.

The A3903 is supplied in a 2 x 2 x 0.55 8-lead DFN package, with exposed thermal pad (suffix EE). This small footprint package is lead (Pb) free, with 100% matt tin leadframe plating. Operating temperature range is -40°C to 85°C.
