Features:

1. TMC2209 is an ultra-quiet motor driver IC for two-phase stepper motor.
2. The TMC2209 is pin compatible with many legacy drivers and the TMC2208.
3. TRINAMICs' advanced StealthChop2 chopper ensures noise-free operation of the motor for high efficiency and motor torque. Its fast current regulation and suppression of resonance combine to achieve high dynamic motion. StallGuard is used for sensorless homing to prevent stalling.
4. Built-in power MOSFET handles motor currents up to 2A RMS with protection and diagnostics for stable and reliable operation.
5. The TMC22209 driver has an improved stealthChop mode (stealthChop2) that works better at higher accelerations.
6. Compared to the TMC2100, the TMC220 output driver (RDSon) has a slightly lower resistance, which reduces power consumption.
