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

Lab Automation and Liquid Handling
Utilizes dual-axis control and high microstepping resolution (up to 1/256) for precise pipetting and sample positioning.
CCTV and Antenna Positioning
Leverages the StealthChop technology for silent movement and SpreadCycle for smooth high-speed tracking.
Office and Building Automation
Ideal for silent blinds, door locks, and paper handling mechanisms in ATMs or cash recyclers.
Battery Powered Devices
Features low standby current and CoolStep load-dependent current control to extend battery life in portable equipment.

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.
