product description:
TMC2209 is an ultra-quiet motor driver IC (original imported chip) for two-phase stepper motors. TMC2209 is pin compatible with many traditional drivers and TMC2208. TRINAMICs' advanced StealthChop2 chopper ensures noise-free operation of the motor, achieving high efficiency and motor torque. The combination of its fast current regulation and resonance suppression function can achieve high dynamic movement. StallGuard is used to return to the origin without sensor to prevent stalling. The built-in power MOSFET can handle motor currents up to 2A RMS, has protection and diagnostic functions, and can achieve stable and reliable operation. An easy-to-use UART interface opens up tuning and control options. Store application tuning in OTP memory. The drive can be set for noise-free operation and very precise operation through a separate pulse direction, thereby realizing a cost-effective and highly competitive solution
TMC series drive comparison table:
1. The operating mode of TMC2209 V2.1 stealthChop is almost silent.
2. The TMC22209 V2.1 driver has an improved stealthChop mode (stealthChop2), which works better at higher acceleration.
3. Compared with TMC2100, the resistance of TMC220 output driver (RDSon) is slightly lower, thereby reducing power consumption.
