Part details & applications

The TMC2241 is a smart, high-voltage stepper driver IC with step and direction control and serial communication interfaces. 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.
