General 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.

The current regulator operates with fixed frequency PWM and uses adaptive mixed current decay to reduce audible motor noise and increase step accuracy.

Overview

AMT49700 Automotive Stepper Driver.

Key Features
