TMC2211ATU+

TMC2211ATU+ is the orderable code for the Analog Devices (Trinamic) TMC2211 smart stepper motor driver in a 38-pin TQFN package (5 x 7 mm), rated for supply voltages up to 65 V and 2 A RMS motor current across -40 °C to +125 °C. It is configured entirely by hardware pins — no register map, SPI bus or driver firmware is needed — and runs the motor through a classic STEP/DIR interface, with ERROR and INDEX feedback outputs and integrated current sensing (ISENSE) that removes external sense resistors from the power stage. For equipment builders this shortens bring-up, removes a whole class of configuration defects, and lets one driver serve 24 V and 48 V motion systems in printers, medical devices, factory automation and stage equipment. Selection advice: choose TMC2211ATU+ (tube) or TMC2211ATU+T (tape and reel) when the controller must stay firmware-free; step up to the register-configurable TMC2241ATU+ (also listed) when runtime configuration is required, and stay with 36 V-class drivers such as TMC2209 only for cost-driven low-voltage axes.
