TRINAMIC's TMC8670 integrates all algorithms for a high-end, fast field-oriented control (FOC) and high-performance real-time fieldbus interface. Suitable for 3-phase BLDC/BLAC motors and 2-phase stepper motors, the TMC8670 embodies decades of experience with motor control.

A single axis embedded servo controller for robotics, manufacturing, and automation, the TMC8670 is designed for an operating voltage of 1.2 V to 3.3 V. Having an SPI-ADC interface, position interpolators, and different position sensor interfaces, the TMC8670 is a high-performance building block that enables a real-time servo controller with only a couple components. It is prepared for typical encoders used in robotics and industrial automation as well as embedded motion control systems.

With a PWM engine including space vector pulse width modulation (SVPWM), the IC is suitable for demanding, low inductance motors and highest dynamic positioning tasks. With all the control loops implemented in dedicated hardware, the TMC8670 executes real-time critical tasks faster than any software-based solution and reduces development time to a minimum.

The TMC8670-BI comes in an FCSG325 (11 x 11) package and meets the -40°C to +125°C automotive grade temperature specification.
