Part details & applications

The TMC4671 is a fully integrated servo controller, providing Field Oriented Control (FOC) 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.
