POWER DRIVER FOR STEPPER MOTORS INTEGRATED CIRCUITS TMC2208/2 & TMC2224 family Datasheet TMC2202, TMC2208, TMC2224 Step/Dir Drivers for Two-Phase Bipolar Stepper Motors up to 2A peak - StealthChop for Quiet Movement - UART Interface Option. APPLICATIONS Compatible Design Upgrade 3D Printers Printers, POS Office and home automation Textile, Sewing Machines CCTV, Security ATM, Cash recycler HVAC FEATURES AND BENEFITS DESCRIPTION 2-phase stepper motors up to 2A coil current (peak) The TMC2202, TMC2208 and TMC2224 are ultra-silent motor driver ICs for two-phase STEP/DIR Interface with 2, 4, 8, 16 or 32 microstep pin stepper motors. Their pinning is compatible setting to a number of legacy drivers. TRINAMICs Smooth Running 256 microsteps by MicroPlyer interpolation sophisticated StealthChop2 chopper StealthChop2 silent motor operation ensures noiseless operation, maximum efficiency and best motor torque. Its fast SpreadCycle highly dynamic motor control chopper current regulation and optional Low RDSon LS 280m & HS 290m (typ. at 25C) combination with SpreadCycle allow for Voltage Range 4.75 36V DC highly dynamic motion. Integrated power- Automatic Standby current reduction (option) MOSFETs handle motor current up to 1.4A Internal Sense Resistor option (no sense resistors required) RMS. Protection and diagnostic features support robust and reliable operation. A Passive Braking and Freewheeling simple to use UART interface opens up Single Wire UART & OTP for advanced configuration options more tuning and control options. Integrated Pulse Generator for standalone motion Application specific tuning can be stored to Full Protection & Diagnostics OTP memory. Industries most advanced STEP/DIR stepper motor driver family Choice of QFN and wettable QFN packages for best fit upgrades designs to noiseless and most precise operation for cost-effective and highly competitive solutions. BLOCK DIAGRAM TRINAMIC Motion Control GmbH & Co. KG Hamburg, Germany TMC220X, TMC2224 DATASHEET (Rev. 1.09 / 2019-JUL-17) 2 APPLICATION EXAMPLES: SIMPLE SOLUTIONS HIGHLY EFFECTIVE The TMC22xx family scores with power density, integrated power MOSFETs, smooth and quiet operation, and a congenial simplicity. The TMC22xx covers a wide spectrum of applications from battery systems to embedded applications with up to 2A motor current per coil. TRINAMICs unique chopper modes SpreadCycle and StealthChop2 optimize drive performance. StealthChop reduces motor noise to the point of silence at low velocities. Standby current reduction keeps costs for power dissipation and cooling down. Extensive support enables rapid design cycles and fast time-to-market with competitive products.
