SLA7075M, SLA7076M,  
SLA7077M, and SLA7078M  
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. 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.  
Contact Allegro® for application information and additional information on  
device performance and logic.
