特性
The TMC5240 is a smart high-performance stepper motor controller and driver IC with serial communication interfaces (SPI, UART) and extensive diagnosis capabilities. It combines a flexible, jerk optimized ramp generator for automatic target positioning with 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).
ADI Trinamic's sophisticated StealthChop2 chopper ensures absolutely noiseless operation combined with maximum efficiency and best motor torque. High integration, high energy efficiency, and a small form factor enable miniaturized and scalable systems for cost effective solutions. The complete solution reduces the learning curve to a minimum while giving best performance in class.
