SLA7071M

DriveMrostor Data Sheet 28210.04A SLA7070M, SLA7071M, SLA7072M, and SLA7073M Motor Driver IC Family The SLA7070M, SLA7071M, SLA7072M, and SLA7073M motor driver ICs feature unipolar drivers. The clock-in type input interface 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-compatibile, 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.
