INTEGRATED CIRCUITS Dedicated Motion Controller for 2-/3-Phase PMSM TMC4671 Datasheet
IC Version V1.00 | Document Revision V1.06 • 2019-Feb-06
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. Features
