The Sanken Power Devices 28210.05 SLA7075M, SLA7076M, SLA7077M, and SLA7078M Motor Drivers are a family of 2-phase stepper unipolar drivers. They feature a clock-in type input interface that allows simplified control logic, and options for built-in sense current detection and load circuit short or open protection (patent pending) provide lower loss and lower thermal resistance. All products in the SLA7070M series are pin-compatible, supporting rapid design of application variants. The built-in excitation distribution circuit (sequencer) allows motor control using only the CLOCK signal for simple operations (rotate/stop), with motor speed control by frequency input into CLOCK pin. This eliminates logic signal lines required for conventional phase-input methods, and reduces demand on heavily-used CPUs.
This document describes the SLA7075M, SLA7076M, SLA7077M, and SLA7078M motor driver ICs, which are 2-phase stepper unipolar drivers. The family features a clock-in type input interface for simplified control logic and includes options for built-in sense current detection and load circuit short or open protection. All products in the series are pin-compatible, supporting rapid design of application variants.
