TMC4670 Field Oriented Control (FOC) Servo Controller Chip

TRINAMIC's FOC controller chip keeps development times of precise and efficient servo controllers to a minimum

Image of TRINAMIC's FOC Servo Controller ChipTRINAMIC's TMC4670 is a single-axis servo motor controller for industrial automation, embedded servo control, and other automated equipment applications. It is suitable for 3-phase BLDC and 2-phase stepper motors. The device is designed for an operating voltage of 1.2 V, 2.5 V, and 3.3 V. The device provides an a/b/n incremental, digital Hall, analog Hall and analog Sin/Cos encoder, and SPI interface.

With a current control loop and PWM frequency configurable between 25 kHz and 200 kHz it is suitable for demanding, low inductance motors and highest dynamic positioning tasks. With all the control loops implemented in dedicated hardware, TMC4670 executes the real time critical tasks faster than any software based solution and keeps the development time to a minimum.
