TMC2240ATJ+

TMC2240ATJ+ is a 36V 2ARMS+ smart integrated stepper driver with S/D and SPI. It combines industries’ most advanced stepper motor driver based on the 256 microsteps built-in indexer and two fully integrated 36V, 3.0AMAX H-Bridges plus non-dissipative integrated current sensing (ICS). High integration, high energy efficiency, and a small form factor enable miniaturized and scalable systems for cost effective solutions while giving best in class performance. It features abundant diagnostics and protections such as short protection/OCP, thermal shutdown, undervoltage lockout (UVLO). Typical applications are textile, sewing machines, knitting machines, lab and factory automation, 3D printers, ID printers/card printers, liquid handling, medical applications, office automation and paper handling, POS, massage chairs, ATM, cash recycler, bill validators, cash machines, CCTV, security, pumps and valve control, heliostat and antenna positioning.

• Voltage range from 4.5V to 36VDC
• Fully integrated lossless current sensing, motor phase and chip temperature measurement
• Step/direction (S/D) interface with MicroPlyer step interpolation, general-purpose analogue input
