TMC5072-LA
Overview
The TMC5072-LA is a high-performance dual-axis stepper motor controller and driver IC integrated into a single QFN-48 package. It combines two flexible SixPoint ramp generators with powerful drivers capable of delivering up to 1.1A RMS per motor from a 5V to 20V supply. This component is specifically designed for applications requiring extremely quiet operation and precise motion control without the need for external power MOSFETs.
Why Choose This Part
The integration of StealthChop allows for nearly silent motor operation at low speeds, while SpreadCycle provides high-speed current control without resonance issues. Its internal SixPoint ramp generators significantly reduce the computational load on the system microcontroller by handling complex acceleration curves autonomously. Furthermore, the small 7x7mm QFN package minimizes PCB footprint for dual-axis designs.
Applications
Getting Started
Engineers can evaluate the chip using the TMC5072-EVAL-KIT, which interfaces with the Landungsbruecke connection board. Software development is supported through the TMCL-IDE, which allows for real-time parameter tuning and script generation. Communication with the host is typically handled via the SPI interface for configuration and motion commands.
