L9935
Two-phase stepper motor driver
Feature summary
■ 2 x 1.1A full bridge outputs
■ Integrated chopping current regulation
■ Minimized power dissipation during flyback
■ Output stages with controlled output voltage
slopes to reduce electromagnetic radiation
■ Short-circuit protection of all outputs
■ Error-flag for over load, open load and over
temperature pre alarm
■ Delayed channel switch on to reduce peak
currents
■ Max. operating supply voltage 24V
■ Standby consumption typically 40A
■ Serial interface (SPI)
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.
