The TMC3241 is a miniaturized, smart, high-power, three-phase stepper motor controller and driver IC with SPI and extensive diagnostic capabilities. Highest integration, high energy efficiency, and a small form factor enable miniaturized, scalable, and cost-effective motor drive solutions perfectly suited for Nema 17, Nema 23, and even Nema 24 steppers, or for three-phase PMSM motors in open loop control.
The TMC3241 allows operation using step and direction input as well as through its integrated motion controller. It combines a smart 1024 sine wave step motor driver for up to 171 microsteps, and three integrated 65V, 4.2A RMS, 6A peak H-bridges plus non-dissipative integrated current sensing (ICS). ICS eliminates bulky external sense resistors, resulting in space and power savings. The integrated power MOSFETs' low impedance of ~40mΩ ensures high efficiency and low heat generation. Abundant diagnostics include temperature and voltage ADC, and a full set of protection functions like short protection and thermal shutdown.
It comes in a compact, near chip-scale, thermally-optimized, 30-pin, 6mm × 6mm, FC2QFN package.
