Description

This document describes the function and features of SLA7080M

series, which are unipolar 2-phase stepping motor driver ICs.

Four levels of output current are available from the incorporated

MOSFETs, corresponding to the rated output current ratings.

All current ratings are available with protection against motor

coil shorts or motor open wire detection.

The SLA7080M series has a multichip structure, for enhanced

thermal dispersion. The Control IC (MIC), four power elements

(MOSFET), and dual sense resistors, are all separate ICs.

Built-in sense resistors for each phase allow accurate track-

ing of performance without additional external components.

Low-power sleep mode as well as reduced power during PWM

off-time maximize energy savings.

Package: 23-pin ZIP (type SLA)
