TWO-PHASE STEPPER MOTOR DRIVER

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.

Two-phase stepper motor driver

Features ■ 2 x 1.1 A 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
