## Use cases

- robot arm
- diy qdd
- industrial servo

## Notes

Driver/controller IC (not a motor, so no torque/weight rating). Fully integrated hardware-FOC servo controller IC for BLDC/PMSM/stepper/DC (not a turnkey board); paired with a power stage or reference design. Reference designs span voltage/current: TMC4671-TOSV-REF 12-36V up to 6A RMS; TMC4671-LEV-REF up to 55V / ~500W. Control via SPI/UART plus Step/Dir; PWM 25-100 kHz; supports many encoder types. Board/IC price varies by vendor (not listed here).
