TMC2209-LA-T Ultra-Silent Stepper Motor Driver UART 28-QFN
The TMC2209-LA-T is a high-performance, ultra-silent bipolar stepper motor driver IC from ADI Trinamic, engineered for precise motion control in noise-sensitive and space-constrained applications. Operating from a 4.75V to 29V supply, it drives two-phase stepper motors up to 2.8A peak (2A RMS) with integrated low RDSon (170mΩ) power MOSFETs. Housed in a compact 5x5mm 28-pin QFN package with an exposed thermal pad, it combines advanced StealthChop2™ silent operation, StallGuard4™ sensorless stall detection, and a flexible UART/Step/DIR interface. Fully optimized for high efficiency, reliability, and low heat generation, it supports -40°C to +125°C operation, making it ideal for industrial, consumer, and battery-powered designs requiring quiet, accurate motor control.
TMC2209-LA-T Motor Driver Key Features
● StealthChop2™ Technology: Delivers completely noiseless motor operation with maximum torque and efficiency.
● High Precision Microstepping: Up to 256 microsteps via MicroPlyer™ interpolation; hardware-configurable 8/16/32/64 microstep settings.
● StallGuard4™: Sensorless load/stall detection for homing, end-stop, and collision avoidance without external sensors.
● CoolStep™: Dynamic current control reducing power consumption by up to 75% and lowering heat.
● Dual Control Interfaces: Simple Step/Dir input plus single-wire UART for advanced configuration and OTP programming.
● Integrated Protection: Over-temperature, over-current, short-circuit, and under-voltage protection with diagnostic feedback.
