The TMC2240 is a smart high-performance stepper motor driver IC with serial communication interfaces (SPI, UART) and extensive diagnosis capabilities. It combines industries’ most advanced stepper motor driver based on the 256-usteps built-in indexer and two fully integrated 36V, 3.0A (max) H-Bridges plus non-dissipative Integrated Current Sensing (ICS).
TMC2240 features abundant diagnostics and protections such as short protection / OCP, thermal shutdown, under voltage lockout. During thermal shutdown and under voltage lockout events the driver is disabled. Furthermore, TMC2240 provides functions to measure the driver temperature, estimate the motor temperature, and measure one external analog input.
