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, support-
ing 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.
