TMC2209 pinning is similar to a number of legacy drivers as well as to the TMC2208. TRINAMICs sophisticated Stealth Chop2 chopper ensures noiseless operation, maximum efficiency and best motor torque. Its fast current regulation and optional bination with Spread Cycle allow highly dynamic motion while adding. Stall Guard for sensorless homing. The integrated power MOSFETs handle motor currents up to 2A RMS with protection and diagnostic Features for robust and reliable operation. A simple to use UART interface opens up tuning and control options. Store application tuning to OTP memory. Industries’ most advanced STEP/DIR...
