FEATURES AND BENEFITS 2-phase stepper motors up to 2A coil current (peak) STEP/DIR Interface with 2, 4, 8, 16 or 32 microstep pin setting Smooth Running 256 microsteps by Micro Plyer™ interpolation Stealth Chop2™ silent motor operation Spread Cycle™ highly dynamic motor control chopper Low RDSon LS 280mΩ & HS 290mΩ (typ. at 25°C) Voltage Range 4.75… 36V DC Automatic Standby current reduction (option) Internal Sense Resistor option (no sense resistors required) Passive Braking and Freewheeling Single Wire UART & OTP for advanced configuration options Integrated Pulse Generator for standalone motion Full Protection & Diagnostics Choice of QFN and wettable QFN packages for best fit BLOCK DIAGRAM DESCRIPTION The TMC2202, TMC2208 and TMC2224 are ultra-silent motor driver ICs for two-phase stepper motors. Their pinning is patible to a number of legacy drivers. TRINAMICs sophisticated Stealth Chop2 chopper ensures noiseless operation, maximum efficiency, and best motor torque. Its fast current regulation and optional bination with Spread Cycle 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 petitive solutions.
