TMC2225-SA-T

TMC2225-SA-T is a TMC2225 ultra-silent motor driver IC for two-phase stepper motors. Their pinning is compatible with a number of legacy drivers. TRINAMIC's sophisticated StealthChop2 chopper ensures noiseless operation, maximum efficiency, and the best motor torque. Its fast current regulation and optional combination with SpreadCycle allow for highly dynamic motion. Integrated power-MOSFETs handle motor current up to 1.4A RMS. Protection and diagnostic features support robust and reliable operation. A simple-to-use UART interface opens up more tuning and control options. Application-specific tuning can be stored 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. Typical applications are compatible design upgrades, 3D printers, printers, POS, office and home automation, textile, sewing machines, CCTV, security, ATM, cash recycler, HVAC.
