The TCM5161 Highly compact, powerful cDriver™ from Trinamic

With the TMC5161, Trinamic extends their fully integrated cDriver™ ICs with an integrated motor controller and driver for 2-phase stepper motors up to 3.5A RMS and 8…40V.

Trinamic - TMC5161

After the successful launch of the TMC5160 early 2018, Micromech announces the Trinamic TMC5161. This 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 is a highly compact stepper motor controller and driver IC. Its power stage is optimized for lowest power dissipation and highest dynamics with Nema 17 and Nema 23 motors. It combines a flexible ramp generator for automatic target positioning with industries’ most advanced stepper motor driver.
Based on TRINAMICs sophisticated spreadCycle and stealthChop choppers, it ensures absolutely noiseless operation combined with maximum efficiency and best motor torque. High integration, high energy efficiency and a small form factor enable miniaturized and scalable systems for cost effective solutions. The complete solution reduces learning curve to a minimum while giving best performance in class. Interface-compatible to TMC5160.
