A4992 - Automotive Stepper Driver

Description

The A4992 is a flexible microstepping motor driver with integrated phase current control and a built-in translator for easy operation.

It is a single chip solution designed to operate bipolar stepper motors in full, half, quarter, eighth, and sixteenth step modes, at up to 28 V.

Features

  • Low RDS(on) outputs, 0.5 Ω source and sink typical.
  • Continuous operation at high ambient temperature.
  • 3.5 to 50 V supply operation.
  • Adaptive mixed current decay.
  • Synchronous rectification for low power dissipation.
  • Internal overvoltage and undervoltage lockout.
  • Hot warning and overtemperature shutdown.
  • Crossover-current protection.
  • Short circuit and open load diagnostics.
  • Stall detect features.
  • Co.
