A3901 Datasheet PDF - Allegro MicroSystems

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.

●Features and Benefits

●▪Low RDS(on) outputs

●▪ Full- and half-stepping capability

●▪ Small package

●▪ Forward, reverse, and brake modes for dc motors

●▪ Sleep mode with zero current drain

●▪ PWM control up to 250 kHz

●▪ Crossover-current protection

●▪ Thermal shutdown (TSD)
