1. Introduction,Features and Applications

Introduction

The M542H is an economical microstepping driver based on patented technology of Sunwind. It is
suitable for driving 2-phase and 4-phase hybrid stepping motors. By using the advanced bipolar
constant-current chopping technique, it can output more speed and torque from the same
motor,compared with traditional drivers, such as L/R drivers. Its 3-state current control technology allows
coil currents to be well controlled and with relatively small current ripple, therefore less motor heating is
achieved.
