BDCC

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.

Key Features

  • 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)
