Integrated Circuits

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. Based on Trinamic's 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.
