2-Phase Stepping Motor Driver 14.4V 20-Pin PowerSO T/R

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.

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 load and over temperature pre alarm

Delayed channel switch on to reduce peak currents

Max. operating supply voltage 24 V

Standby consumption typically 40 µA

Serial interface (SPI)
