Silent5160

Product Introduction¶

TMC5160

The TMC5160 is a high power stepper motor controller and driver IC with serial communication interfaces. It combines a flexible ramp generator for automatic target positioning with industries’ most advanced stepper motor driver. Using external transistors, highly dynamic, high torque drives can be realized. Based on Trinamic's sophisticated SpreadCycle™ and StealthChop™ choppers, the driver 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. TMC5160-WA uses a wettable flank package to allow optical inspection of the soldering joints.
