AMT49700 - Automotive Stepper Driver

Description

The AMT49700 is a flexible microstepping stepper motor driver with integrated phase current control, a built-in translator, and simple motion control.

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

  • Peak motor current up to 1.6 A at 28 V.
  • Low RDS(ON) outputs, 0.5 Ω source and sink typical.
  • Continuous operation at high ambient temperature.
  • 3.7 to 42 V supply operation.
  • Adaptive mixed current decay.
  • Synchronous rectification for low power dissipation.
  • Output slew control and PWM frequency spreading for EMC noise reduction.
  • Internal overvoltage and undervoltage lockout.
  • Hot warning and overtemperature shutdown.
