TRINAMIC’s new highly compact stepper motor controller and driver chip covers a wide spectrum of applications

stepper motorA stepper motor is often an ideal choice for industrial automation and various other applications. With the TMC5161, TRINAMIC Motion Control is offering engineers dealing with stepper motors a highly-integrated motor controller and driver for 2-phase stepper motors up to 3.5A RMS and 8…40V. The chip claims high integration, high energy efficiency and a small form factor to enable miniaturized and scalable systems for cost-effective solutions.

The solution 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 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 complete solution reduces the learning curve to a minimum while giving the best performance in class, claimed the firm.

“The TMC5161 combines our technological innovations successfully into a single device. Moreover, it achieves a new maximum for motor voltage and current specs in a monolithic motion controller with integrated MOSFETs,” explains Michael Randt, Founder and CEO of Trinamic. As always, ease of use was an important guideline for our designers, as well as cost efficiency. The result is an integrated IC that enables superior stepper motor control that offloads designers of the need for specialized motor control know-how.
