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 40uA Serial interface (SPI)
PowerSO-20

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.
