Allegro Intos SLA706xM Series Motor Driver ICs

August 20, 2003 by Jeff Shepard

Allegro MicroSystems Inc. (Worcester, MA) introduced its new family of Sanken, unipolar, microstepping, two-phase, constant-current, motor driver ICs with built-in sequencers. The SLA706xM Series is a complete motor driver family with a built-in translator designed to operate unipolar stepper motors with a simple step input. There is no need for phase-sequence tables, high-frequency control lines, or complex interfaces to program.

For half-, quarter-, eighth- and sixteenth-microstepping, the choice of products are the SLA7060M, SLA7061M and SLA7062M. The SLA706xM Series includes a pulse-width modulated (PWM), constant-current, control method; and a synchronous PWM chopping function for two phases of motor coils to prevent motor noise at the hold mode and sleep mode for reducing the IC input current at stand-by mode. The SLA7060xM Series is targeted toward circuit microstepping motor-controller applications.

The SLA7060xM family has a 10-week lead time to market. The SLA7060M is priced at $1.92, the SLA7061M is $2.10 and the SLA7062M is $2.35. The family is offered in a 21-pin, single in-line, power-tab package.
