TRINAMIC’s TMC5160 single-axis driver IC addresses 2-phase bipolar stepper motors

TRINAMIC Motion Control announced the TMC5160 single-axis stepper motor driver IC with serial communication interfaces for 2-phase bipolar stepper motors with external MOSFETs for up to 20A motor current per coil. The device integrates a powerful stepper motor driver and a dedicated motion controller in one single chip, transforming digital information into physical motion that’s smooth, precise and reliable. 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 with the TMC “Landungsbrücke”.
The TMC5160-TA is sampling now. Production volumes, the evaluation board (TMC5160-EVAL), evaluation kit (TMC5160-EVAL-KIT) and a breakout board (TMC5160-BOB) will be available from March 2018. Offered in a QFP48 (7mm x 7mm) package, the TMC5160-TA is priced at USD 3.26 in 1,000 unit volumes.
