TMC2211

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 non-dissipative 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 cost effective solutions. The complete solution reduces the learning curve to a minimum while giving best-in-class performance. The H-bridge field-effect transistors (FETs) have very low impedance, resulting in high driving efficiency and minimal heat generated. The typical total R_ON (high side + low side) is 0.31Ω.

The maximum RMS current per H-bridge is 2A with V_S = 24V and 1.7A with V_S = 48V supply at room temperature, assuming a four-layer PCB.

Due to thermal restrictions, the applicable RMS current depends on environment temperature, duty cycle, and the thermal characteristics of the application (PCB ground planes, heatsink, ventilation).

The maximum full-scale current per H-bridge is IFS = 3.0AMAX and can be set by an external resistor connected to I_REF. This current is defined as the maximum current setting of the embedded current drive regulation circuit.
