Silent stepper motor driver 5 to 36V, up to 1.4A with S/D and UART Interface, 256 µSteps, SpreadCycle and Stealthchop2

The TMC2226 is an ultra-silent motor driver IC for two phase stepper motors. ADI 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.
