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 tables, high-frequency control lines, or complex interfaces to program.
The
CMOS logic section provides the sequencing logic, direction, control, synchronous/asynchronous PWM operation, and a “sleep” fu...
