The TMC2226 is an ultra-quiet driver for two-phase stepper motors.
The StealthChop2 TRINAMIC ensures quiet operation, maximum efficiency and best motor torque. Its fast current regulation and optional combination with SpreadCycle enable highly dynamic motion. StallGuard for sensorless homing. Integrated power MOSFETs handle motor currents up to 2A RMS with protection and diagnostic function for robust and reliable operation.
It is an easy-to-use UART interface that opens to tuning and control options.
Settings can be stored in OTP memory.
The industry's most advanced stepper motor family driver implements with this model new designs for quieter and higher precision operation for cost-effective and highly competitive solutions.
