TMC2041 Dual-Axis Stepper Motor Driver

TRINAMIC announces the dual-axis stepper motor driver IC with integrated MOSFET power switches. The TMC2041 delivers 1.5 A (peak) at 26 V supply voltage per motor, meaning it is suitable for driving motors from NEMA 8 to NEMA 17. Based on TRINAMIC's high-performance spreadCycle™ chopper, it allows for precise and smooth motor operation and up to 75% energy savings using coolStep™.

With an easy to use step and direction interface and the option to read back a variety of diagnostics values via SPI, the TMC2041 is designed to work with common motion control algorithms. The integrated step pulse interpolation engine microPlyer™ accepts a step pulse resolution of 16 pulses per full step while interpolating the current control to 256 microsteps, resulting in superior smoothness of the motion.

The compact TMC2041 is ideally suited for office automation, 3D printers, medical applications, and other applications where machinery works in close proximity to human operators, as these environments often have strict noise limitations. It is available in a QFN48 (7 mm x 7 mm) package. An evaluation kit, proven and tested reference designs, and a package of libraries allow for fast design in.
