Suited for stepper motors of 5…29 V up to 2.8 A (peak), the TMC2226 combines world’s best stepper motor driver technology with simple step/dir interface for ease of use.
TRINAMIC Motion Control announces their latest stepper motor driver for 2-phase bipolar stepper motors. Programmable via UART and featuring some of Trinamic’s latest-generation technologies, the highly dynamic stepper driver is ideal for design upgrades with compatible drivers.
Ensuring noiseless operation with StealthChop2, the chip enables smooth and silent stepper motors with for everyday use. At the same time, the sophisticated chopper increases efficiency and motor torque compared with normal choppers. Once tuned, Engineers can simply store the settings on the OTP memory and use it for standalone motion thanks to the internal pulse generator. This makes the TMC2226 an effective and cost-efficient solution for printers and POS devices, office and home automation, textile, security, ATMs and cash recyclers, as well as battery-operated equipment.
Besides StealthChop2, the chip features StallGuard4 for sensorless load- and stall detection, CoolStep to minimize energy consumption, and SpreadCycle to keep noise and vibrations at a minimum while driving the motor at higher speeds. Furthermore, the low RDSon and automatic power down increase energy-efficiency, making it one cool step/direction driver with appealing simplicity.
The TMC2226 comes in a thermally optimized HTSSOP28 package (9.7 × 6.4 mm) for optical inspection, has full protection and diagnostics and offers an internal sense resistor option. The chip, evaluation board, and breakout board are available from beginning of May via Trinamic’s official distribution channels.
