製品概要

The TMC5262-EVKIT is part of the TRINAMIC evaluation board system. The boards included in this kit, in combination with the TMCL-IDE, allow for an uncomplicated first evaluation of the TMC5262, while also providing full control of all its features.

The TMC5262 is a miniaturized, smart, high-power, single-axis stepper motor controller and driver IC with SPI and extensive diagnostic capabilities. Highest integration, high energy efficiency, and a small form factor enable miniaturized, scalable, and cost-effective motor drive solutions perfectly suited for Nema 17, Nema 23, and Nema 24 steppers.

StealthChop+ ensures noiseless operation and maximum efficiency, optimal motor torque control, and dampening of midrange motor resonances for a smoothly running motor with low mechanical vibrations. Combined with StallGuard+, CoolStep+, and μDcStep, this results in a highly efficient and versatile stepper motor driver. An unloaded Nema 17 motor automatically runs with as low as a few 10mA of supply current.

The TMC5262 combines a flexible, 8-point ramp generator for automatic positioning with a smart 256-microstep motor driver and two integrated 65V, 4.25ARMS, 6A peak H-bridges plus nondissipative integrated current sensing (ICS). ICS eliminates bulky external sense resistors, resulting in space and power savings.

Abundant diagnostics include an on-chip scope interface for tuning and checking (RT-OCSI), temperature and voltage ADC, and a full set of protection functions such as short protection and thermal shutdown.
