SLA7070MPRT Overview
This document describes the SLA7070MPRT series, which are unipolar 2-phase stepping motor driver ICs. The SLA7070MPRT series employs a clock input method as a control signal input method, enabling full control of the device operation using only a few signal lines, instead of the conventional phase input method that requires about 10 signal lines. This allows simplification of the circuit design and a reduced...
