DESCRIPTION
The A3901 is a dual full-bridge motor driver, designed for low voltage portable applications involving bipolar stepper or brush DC motors. The outputs have been optimized for low voltage drop, with currents up to ±400 mA (±800 mA with outputs paralleled) and an operating voltage range of 2.5 to 5.5 V.
