TMC4671 Servo Controller IC

TRINAMIC's fully integrated field-oriented control (FOC) servo controller IC provides field-oriented control for BLDC/PMSM and 2-phase stepper motors, DC motors, and voice coils

Image of Trinamic's TMC4671 Servo Controller IC TRINAMIC's TMC4671-LA is designed based on input from market design leaders in the fields of e-mobility, medical devices, lab automation, robotics, factory automation, and pumps and blowers. The TMC4671-LA addresses these markets by embedding all necessary control loops in rugged, reliable state-machines. By offloading real-time critical tasks from the processor and software and implementing all control functions in hardware, the TMC4671 offers a crucial benefit by taking care of all control functions itself.
