SLA7060M Datasheet (Allegro MicroSystems) - UNIPOLAR STEPPER-MOTOR TRANSLATOR/DRIVERS

SLA7060M, UNIPOLAR STEPPER-MOTOR TRANSLATOR/DRIVERS

Device operation.

These devices are complete microstepping motor drivers with built in translator for easy operation with minimal control lines.

They are designed to operate unipolar stepper motors in half-, quarter-, eighth-, and sixteenth-step modes.

The current in each of the four outputs, all n-

PRELIMINARY INFORMATION (subject to change without notice) September 24, 2003 SLA7060M THRU SLA7062M UNIPOLAR STEPPER-MOTOR TRANSLATOR/DRIVERS Combining low-power CMOS logic with high-current, high-voltage power FET outputs, the Series SLA7060M translator/drivers provide complete control and drive for a two-phase unipolar stepper motor with internal fixed off time and pulse-width modulation (PWM) control of the output current in a power multi-chip module (PMCM™).

There are no phase-sequence ta
