Description TMC2209 is an ultra-quiet motor driver IC for two-phase stepper motors. TMC2209 is compatible with many traditional drivers and TMC2208 pin. The advanced chopper can ensure noise-free operation of the motor, achieving high efficiency and motor torque. Its fast current adjustment and resonance suppression function combination can achieve high dynamic movement. Stall Guard is used to return to the origin without sensor to prevent stalling.
