The A3987 is a microstepping motor driver with an integrated translator for bipolar stepper motors, supporting full to sixteenth-step modes up to 50V and 1.5A. It features an automatic current decay mode selection for reduced noise, synchronous rectification, and internal protection including thermal shutdown, UVLO, and crossover current.
