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.

device performance and logic.
