Description

Combining low-power CMOS logic with high-current, high-voltage power FET outputs, the SLA7062M is a motor driver and controller designed for a two-phase unipolar stepper motor. It provides complete control and drive with internal fixed off time and pulse-width modulation (PWM) control of the output current. The SLA7062M is a cost-effective, multi-chip solution that eliminates the need for phase-sequence tables, high-frequency control lines, or complex interfaces to program.
