L9935:Two-Phase Stepper Motor Driver

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.

Key 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)
