From Trinamic: TMC4670 - World's most refined FOC servo controller on a chip

Jul 17, 2017

Embodying decades of experience in motor control, Trinamic’s TMC4670 is the world’s most refined embedded servo controller on a chip. Suited for 3-phase BLDC motors, BLAC motors and 2-phase stepper motors, it integrates all algorithms for a high-end and fast field oriented control.
Prepared for typical encoders
Being the first of a whole new family, the TMC4670 is a single-axis servo motor controller for industrial automation, embedded servo control and other automated equipment applications. The device is designed for an operating voltage of 1.2 V, 2.5 V and 3.3 V and has various position feedback options such as a/b/n incremental, digital hall, analog hall, analog Sin/Cos encoder and SPI interface. As a result, this controller chip from TRINAMIC Motion Control is prepared for typical encoders used in robotics and industrial automation, as well as embedded motion control systems. It packs two separate encoder units that can be mapped for commutation and positioning.
Faster than software based solutions
The current control loop and a configurable PWM frequency (25 kHz – 200 kHz) make Trinamic’s TMC4670 suitable for demanding, low inductance motors and highest dynamic positioning tasks. With all the control loops implemented in dedicated hardware, the controller chip executes real-time critical tasks faster than any software based solution, while reducing the development time to a minimum.
To further speed up the design process, TRINAMIC Motion Control offers complete end-to-end evaluation kits. The component and an evaluation board for the modular Landungsbrücke system are already available, and the development boards are open-source hardware, freely available for use as a reference design.
The TMC4670 is part of the new, full line of closed-loop motion control ICs.
