Product overview

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.

  • All 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 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)
