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.
