ADITMC5041-LA
Overview
The TMC5041-LA is a dual-axis stepper motor controller and driver IC designed to operate two bipolar stepper motors from a 5.5V to 26V supply. It integrates two power stages capable of delivering up to 1.1A RMS current per motor alongside a sophisticated SixPoint ramp generator for autonomous motion control. By offloading real-time motion calculations from the host MCU, it simplifies the development of multi-axis systems while ensuring quiet and precise motor operation.
Why Choose This Part
The IC features StealthChop for absolutely silent motor operation and StallGuard2 for sensorless load detection, eliminating the need for physical limit switches. Its integrated ramp generator supports complex SixPoint profiles, allowing for smooth acceleration and deceleration without constant MCU intervention. The device also includes CoolStep technology, which automatically optimizes motor current to reduce heat dissipation and energy consumption.
Applications
Key Specifications
Getting Started
Designers can evaluate the chip using the TMC5041-EVAL board and the Landungsbruecke interface board. Configuration is performed via the SPI interface using the TMCL-IDE software, which allows for real-time tuning of chopper and ramp parameters. Hardware integration requires a 48-pin QFN footprint with a thermal pad for adequate heat dissipation of the internal power MOSFETs.
