Analog Devices 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 nondissipative integrated current sensing (ICS). The complete solution reduces the learning curve to a minimum while giving best-inclass performance.

GENERAL DESCRIPTION

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 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. The maximum RMS current per H-bridge is 2A with VS = 24V and 1.7A with VS = 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 IREF. This current is defined as the maximum current setting of the embedded current drive regulation circuit.
