Description

The L9935 is a two-phase stepper motor driver

circuit suited to drive bipolar stepper motors.

The device can be controlled by a serial interface

(SPI). All protections required to design a well

protected system (short-circuit, over temperature,

cross conduction etc.) are integrated.
