Availability: In stock

The converter is the key to easy implementation of the A4988. As long as the "step" input carries in a pulse, you can drive the motor to produce micro-step. There is no need for phase sequence tables, high frequency control lines or complex interface programming. The A4988 interface is ideal for complex microprocessors that are not available or overloaded.

Introduction

This stepper motor driver is powered by A4988, a DMOS microstep driver with converter and overcurrent protection. It is available in full, half, 1/4, 1/8 and 1/16 stepping modes to operate bipolar stepper motors with output drive performance up to 35 V and ± 2A. The A4988 includes a fixed turn-off time current regulator that operates in slow or mixed decay mode.
