TMC5161 cDriver™ ICs

Trinamic Motion Control's TMC5161 cDriver solution is an easy to use building block with a powerful integrated MOSFET driver stage and complete motion control features, including innovative current regulation.

The TMC5161 achieves a new maximum for motor voltage and current specs in a monolithic motion controller with integrated MOSFETs. The result is an integrated IC that enables superior stepper motor control that offloads designers of the need for specialized motor control know-how.

Designed with ease of use in mind, the powerful chip can be set up and evaluated easily using Trinamic's free, easy to use TMCL-IDE software and the modular evaluation kit. This not only minimizes development time, but it also allows engineers to quickly try out different parameters for the optimal result, including Trinamic technologies that are in high demand such as SixPoint™ ramping, StealthChop2™, StallGuard2™, and more.

The cDriver covers a wide spectrum of applications from battery powered, high-efficiency systems up to embedded applications, ideal for robotics and industrial drives, textile, lab and office automation, medical drives, and next-generation desktop manufacturing applications. The complete solution reduces the learning curve to a minimum while giving the best performance in class.

The TMC5161 comes in a compact 10 mm x 10 mm aQFN package. The cDriver will also be offered as an evaluation kit and breakout board for quick evaluation and parameterization.
