The TMC2226 is an ultra-silent motor driver IC for two phase stepper motors. Maximum efficiency and best motor torque. Its fast current regulation and optional combination allow highly dynamic motion while adding. StallGuard4 provides sensor less 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.
