Mon 12th Mar 2018 - Go big with the TMC5160 controller/driver IC

TMC5160This single-axis stepper motor driver IC with serial communication interfaces is developed for 2-phase bipolar stepper motors with external MOSFETs for up to 20A motor current per coil.

 

"It successfully combines our technological innovations into a single device that achieves a new maximum for motor voltage and current specs with external N-channel MOSFETs,” explains Michael Randt, Founder and CEO of Trinamic."Ease-of-use was the guideline for our designers, as well as cost efficiency. By integrating a powerful stepper motor driver and a dedicated motion controller in one single chip, the TMC5160 directly transforms digital information into physical motion that’s smooth, precise and reliable."

 

In fact, it’s so easy to use that you only need the target positions. All stepper motor logic takes place within the TMC5160 itself – there’s no need for software when driving NEMA17 up to NEMA34 and bigger motors. Connected to a host microcontroller through an industry standard SPI or step/direction interface, the TMC5160 performs all real-time position and velocity stepper motion calculations.

 

Extending the TMC2100, TMC2130, and TMC5130 family to higher voltages and motor currents, the chip packs the company’s successful SpreadCycle™, StealthChop™ and SixPoint™ technologies for microstepping with up to 256 microsteps per full step, silent operation and an advanced ramp generation profile maxing out the motor’s torque characteristics for rapid positioning. Designed for CNC machines, textile machines, lab automation, factory automation and other domains using powerful motors where smooth, quiet and precise motion is required.

 

To minimize the application development time, Trinamic provides the comprehensive application development package TTAP which includes code examples, EDA libraries, and reference designs. Fast evaluation is realized using Trinamic’s intuitive PC-based software TMCL-IDE and the modular evaluation kit.

 

The TMC5160-TA, evaluation board (TMC5160-EVAL), evaluation kit (TMC5160-EVAL-KIT) and a breakout board (TMC5160-BOB) is available now.  For more information on Trinamic products contact Micromech on 01376 333333 or sales@micromech.co.uk
