TMC4671

FOC Motion-Controller for 2- [&] 3-Phase Motors (BLDC, PMSM [&] Stepper)

The TMC4671 is a fully integrated servo controller, providing Field Oriented Control for BLDC/PMSM and 2-phase Stepper Motors as well as DC motors and voice coils.

All control functions are implemented in hardware. Integrated ADCs, position sensor interfaces, position interpolators, enable a fully functional servo controller for a wide range of servo applications.
