L6219 - Stepper motor driver

Description

The L6219 is a bipolar monolithic integrated circuits intended to control and drive both winding of a bipolar stepper motor or bidirectionally control two DC motors.

Features

  • Able to drive both windings of bipolar stepper motor.
  • Output current up to 750 mA each winding.
  • Wide voltage range: 10 V to 46 V.
  • Half-step, full-step and microstepping mode.
  • Built-in protection diodes.
  • Internal PWM current control.
  • Low output saturation voltage.
  • Designed for unstabilized motor supply voltage.
  • Internal thermal shutdown.
