TMC2209 V2.1 Super Silent Stepper Motor Driver
TMC2209 is an ultra-quiet motor driver IC (original imported chip) for two-phase stepper motor . The TMC2209 is pin compatible with many legacy drivers and the TMC2208. TRINAMICs’ advanced StealthChop2 choppers ensure noise-free operation of the motor for high efficiency and motor torque. Its fast combination of current regulation and suppression of resonance provides high dynamic motion. StallGuard is used for sensorless homing to prevent stalling. The built-in power MOSFET handles motor currents up to 2A RMS with protection and diagnostics for stable and reliable operation. An easy-to-use UART interface opens the tuning and control options. Store application tuning to OTP memory. A separate pulse direction allows the drive to be set up for noise-free operation and very precise operation for a cost-effective and competitive solution
