  • Automatic standby current reduction
  • microPlyer - microstep interpolator for increased smoothness of microstepping
  • stealthChop - for quiet operation and smooth motion
  • stealthChop2 - faster motor acceleration/deceleration than stealthChop (TMC220x/TMC516x)
  • spreadCycle - highly dynamic motor control chopper
  • coolStep - current control for energy savings (TMC2130/TMC2209/TMC516x)
  • stallGuard2 - sensorless motor load detection (TMC2130/TMC516x)
  • stallGuard4 - sensorless motor load detection optimized for stealthChop (TMC2209)
  • dcStep - load dependent speed control (TMC2130/TMC516x)
  • SPI configuration interface up to 4MHz (TMC2130/TMC516x)
  • UART configuration interface up to 500k Baud (TMC220x)
