A3982 Overview

The A3982 is a plete stepper motor driver with built-in translator for easy operation. It is designed to operate bipolar stepper motors in full- and half-step modes, with an output drive capacity of up to 35 V and ±2 A. The A3982 includes a fixed off-time current regulator which has the ability to operate in Slow or Mixed decay modes.

A3982 Key Features

  • Low RDS(on) outputs
  • Automatic current decay mode detection/selection
  • Mixed and Slow current decay modes
  • Synchronous rectification for low power dissipation
  • Internal UVLO and thermal shutdown circuitry
  • Crossover-current protection

A3982 Applications

  • Contact Allegro for additional packing options
