TMC8670-BI

Motor Drivers, Controllers Overview

The TMC8670-BI is a CANopen-over EtherCAT (CoE) field oriented control servo controller designed for torque, velocity, and position control applications. It features a multiphase motor driver architecture housed in a 325-ball BGA package. The device supports high-side and low-side output configurations with load voltages of 1.2V and 3.3V, operating within a supply voltage range of 3.15V to 3.45V. It integrates an SPI-ADC interface, position interpolators, and various position sensor interfaces to enable precise motion control.

Motor Drivers, Controllers Procurement Notes

Verify component authenticity through authorized distributors as the TMC8670-BI is obsolete and no longer manufactured by Analog Devices Inc./Maxim Integrated. Confirm package integrity and pin compatibility due to end-of-life status. Check for valid replacement alternatives from current Trinamic product lines if long-term supply assurance is required for production environments.

Motor Drivers, Controllers Selection Notes

Select this component only for legacy systems requiring specific CoE integration. Ensure design compatibility with the 325-BGA footprint and 3.15V to 3.45V supply requirements. Evaluate alternative modern controllers if new designs are initiated, given the obsolete manufacturing status. Verify firmware support for existing CANopen-over EtherCAT implementations before procurement.
