The TMC2226 is an ultra-silent motor driver IC for two phase stepper motors. TRINAMIC's 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. StallGuard4™ provides 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. Industries’ most advanced Step/Dir stepper motor driver family upgrades designs to noiseless and most precise operation for cost-effective and highly competitive solutions.
