Motor Driver IC Family

The SLA7075M, SLA7076M, SLA7077M, and SLA7078M motor driver ICs feature 2-phase stepper 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.Al1 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.
Contact Allegro for application information and additional information on device performance and logic.
