TMC2209 LA-T describes that TMC2209 is an ultra quiet motor driver IC used for two-phase stepper motors. TMC2209 is similar to many old drivers and TMC2208. TRINAMIC's precise StealthChop2 chopper ensures noise free operation, maximum efficiency, and optimal motor torque. Its fast current regulation and optional combination with SpreadCycle allow for highly dynamic motion when added. StallGuard for sensorless homing. Integrated power MOSFET can handle motor currents up to 2A RMS, with protection and diagnostic functions, enabling robust and reliable operation. The easy-to-use UART interface opens tuning and control options. Store application optimization in OTP memory. The industry's most advanced STEP/DIR stepper motor driver series will be upgraded in design to be noise free and operate with the most precision, achieving cost-effective and highly competitive solutions.
