Overview

  • Up to 171 microsteps (256 sine wave steps) using step/direction interface or 20 Bit SPI™ interface
  • High precision sensorless motor load measurement stallGuard2
  • Energy efficiency and coolness by automatic load dependant motor current regulation coolStep™: Save up to 75% of energy!
  • Internal microstep extrapolation allows 256 wave step smoothness with low frequency step input
  • Dual edge step option allows half step frequency requirement, e.g. for opto-couplers
  • Up to 8A Motor current using external N&P channel MOSFET pairs
  • Synchronous rectification reduces transistor heating
  • 9V to 60V operating voltage (peak)
  • 3.3V or 5V interface
  • QFN32 package for extremely small solution with superior thermal performance
