ADI Trinamic TMC5240x Stepper Motor Controller & Driver ICs

ADI Trinamic TMC5240x Stepper Motor Controller and Driver ICs are equipped with serial communication interfaces (SPI and UART) and extensive diagnosis capabilities. These smart high-performance ICs combine a flexible, jerk-optimized ramp generator with a stepper motor driver. This motor driver is based on the 256 microsteps built-in indexer and two fully integrated 36V, 3A (maximum) H-Bridges plus non-dissipative Integrated Current Sensing (ICS).

The TMC5240x controllers feature a 4.5V_DC to 36V_DC voltage range and abundant diagnostics protections such as short protection/OCP, thermal shutdown, and undervoltage lockout. These motor controllers and driver ICs provide functions to measure the driver temperature, estimate the motor temperature, and measure one external analog input. The TMC5240x ICs are available in a small TQFN32 5mm x 5mm package and a thermally optimized TSSOP38 9.7mm x 4.4mm with an exposed pad. Typical applications include textile, sewing machines, knitting machines, labs, factory automation, 3D printers, ID printers/card printers, ATMs, cash recyclers, bill validators, and cash machines.
