The SLA7042M and SLA7044M are designed for high-efficiency and high-performance microstepping operation of 2-phase, unipolar stepper motors. Microstepping provides improved resolution without limiting step rates, and provides much smoother low-speed motor operation. An automated, innovative packaging technology combined with power NMOS FETs and monolithic CMOS logic/control circuitry advances power multi-chip modules (PMCMs™) toward the complete integration of motion control.
