TMC2209-LA-T

TMC2209-LA-T is an ultra-silent motor driver IC for two phase stepper motors. TMC2209 pinning is similar 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. It is used in 3D printers, printers, POS, office and home automation, textile, sewing machines, CCTV, security, ATM, cash recycler and HVAC.
