Analog Devices Inc. TMC2241 Smart Integrated Stepper Driver
Analog Devices TMC2241 Smart Integrated Stepper Driver is a smart, high-voltage stepper driver IC with step and direction control and serial communication interfaces. It combines an advanced stepper motor driver based on 256 microsteps, a built-in indexer, and two fully integrated 65V, 3.0A maximum H-bridges, plus non-dissipative integrated current sensing (ICs).
Analog Devices' sophisticated StealthChop2 chopper ensures absolutely noiseless operation, combined with maximum efficiency and optimal motor torque.
