DRV8805 Motor Driver

DRV8805 Motor Driver

Texas Instruments' DRV8805 provides an integrated solution for driving unipolar stepper motors. It includes four low-side drivers with overcurrent protection and provides built-in diodes to clamp turn-off transients generated by the motor windings. Indexer logic to control a unipolar stepper motor using a simple step/direction interface is also integrated. Three stepping modes are supported: 2 phase (full-step), 1-2 phase (half-step), and 1-phase (wave drive).

Features
  • 4-channel protected low-side driver
  • Indexer/translator for unipolar stepper motors
  • 8.2 V to 60 V operating supply voltage range
  • Thermally enhanced surface mount package
Applications
  • Gaming machines
  • General unipolar stepper motor drivers
