Application Information SLA7070MPRT Series Unipolar 2-Phase Stepper Motor Driver ICs General Description 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 workload on the control microprocessor. In addition, the SLA7070MPRT series is improved in its reliability by preventing the IC from damage due to abnormal conditions. For example, it has a flag output terminal to signal that a protection circuit has operated.
