SLA7073MS [SANKEN]

The SLA7070MS series are stepper motor driver ICs with built-in sequencer for clock-in stepping control. They support full-, half-, and microstepping (with options for full, half, quarter, eighth, and sixteenth stepping). Key features include: main power supply voltage up to 46V (normal operating range 10-44V), logic supply voltage 3.0-5.5V, maximum output currents of 2.0A and 3.0A, built-in sense resistor for motor current detection, pin-compatible variants, ZIP 23-pin molded package, self-excitation PWM current control with fixed OFF-time (automatically adjusted for microstepping), built-in synchronous rectifying circuit to reduce power dissipation, synchronous PWM chopping to reduce motor noise in Hold mode, sleep mode to reduce input current, and built-in protection against motor coil opens/shorts and thermal shutdown. Optional features include Blanking Time and Input Clock Edge (with branding codes B and W).
