DESCRIPTION
The TMC2209 and TMC2226 are ultra-silent
motor driver ICs for two phase stepper
motors. TMC2209 pinning is compatible to
a number of legacy drivers as well as to
the TMC2208. TRINAMICs sophisticated
StealthChop2 chopper ensures noiseless
operation, maximum efficiency and best
motor torque. Its fast current regulation
and optional combination with SpreadCycle
allow highly dynamic motion while adding.
StallGuard 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
stepper motor driver family upgrades
designs to noiseless and most precise
operation for cost-effective and highly
competitive solutions.
