Description

Manufacturer:ALLEGRO SANKEN
Manufacturer Part No:SLA7026M

Product Overview

The SLA7026M is a high-current PWM unipolar stepper Motor Controller/Driver IC. An automated, innovative packaging technology combined with power FETs and monolithic logic/control circuitry advances power multi-chip modules (PMCM) toward the complete integration of motion control. Highly automated manufacturing techniques provide low-cost and exceptionally reliable PMCMs suitable for controlling and directly driving a broad range of 2-phase, unipolar stepper motors. The three stepper motor multi-chip modules differ primarily in output current ratings (1.5 or 3.0A) and package style. All three PMCMs are rated for an absolute maximum limit of 46V and utilize advanced NMOS FETs for the high-current, high-voltage driver outputs. The avalanche-rated (>=100V) FETs provide excellent ON resistance, improved body diodes and very-fast switching.
