SLA7031M

Overview

The SLA7031M is a unipolar stepper motor driver manufactured by Sanken Electric. It integrates power MOSFETs to drive two-phase or one-half phase excitation motors. The device operates within a supply voltage range of 10V to 46V and delivers a continuous output current of 3A per phase, with peak currents reaching 4A. It supports full-step, half-step, and quarter-step control modes. The component utilizes an 18-ZIP package for through-hole mounting and functions within a junction temperature range of -20°C to 150°C.

Feature Summary

Integrates power MOSFETs for direct driving of unipolar stepper motors
Supports multiple step control modes including full, half, and quarter steps
Designed for wide voltage operation suitable for various power environments

Applications

Unipolar stepper motor control systems
Industrial automation equipment requiring precise positioning
Home appliance motor drives
