Allegro MicroSystems Introduces Two-Phase Unipolar
Microstepping Motor Driver Family 
Worcester, MA - August 15, 2003 — Allegro MicroSystems, Inc. introduces a new family of Sanken unipolar microstepping two-phase constant-current motor driver ICs with built-in sequencer. The SLA706xM series is a complete unipolar microstepping motor driver family with 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, SLA7062M. The SLA706xM series includes a PWM constant-current control method, 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 primarily targeted toward circuit design engineers of microstepping motor-controller applications specifically copy machines, scanners and robots. This family is offered in a 21-pin single in-line power-tab package.
Allegro MicroSystems, Inc. is a supplier of advanced mixed-signal power semiconductors and Hall-effect sensors targeted toward the automotive, communications, computer/office automation, consumer and industrial markets. It maintains a leadership position in the integrated magnetic sensor and integrated motor driver product segments. With over 2,000 employees, Allegro is headquartered in Worcester, MA.
