65V 2ARMS Smart Pin-Configurable Integrated Stepper Driver

The TMC2211 is a high-performance stepper motor driver IC with configuration options through package pins and additional diagnostic outputs. It combines the industry’s most advanced stepper motor driver based on the 256 microsteps, built-in indexer and two fully integrated 65V, 3.0AMAX H-bridges, plus nondissipative integrated current sensing (ICS).

ADI-Trinamic's sophisticated StealthChop2 chopper ensures absolutely noiseless operation combined with maximum efficiency and best motor torque.

High integration, high energy efficiency, and a small form factor enable miniaturized and scalable systems for costeffective solutions. The complete solution reduces the learning curve to a minimum while giving best-inclass performance. The H-bridge field-effect transistors (FETs) have very low impedance, resulting in high driving efficiency and minimal heat generated. The typical total RON (high side + low side) is 0.31Ω.
