MLX90411LLD-BAA-048-SP

Overview

The MLX90411LLD-BAA-048-SP is an automotive-grade, low-noise single-coil fan driver integrated circuit manufactured by Melexis. It features a fully integrated design with a high-sensitivity Hall effect sensor for commutation. The device supports open-loop control and includes programmable dynamic PI settings. It operates within a supply voltage range of 3V to 28V and provides an output current capability of up to 600mA. The component is housed in a compact UTDFN-6 package (2.5x2mm) suitable for surface mount installation. It holds AEC-Q100 qualification and is designed for applications requiring robust performance in harsh environments.

Feature Summary

Fully integrated single-coil fan driver with built-in high-sensitivity Hall effect sensor
Supports open-loop speed control with programmable dynamic PI settings
Integrated power clamp protection for system stability
Automotive-grade reliability with AEC-Q100 qualification

Applications

Automotive LED headlight cooling fans
Vehicle seat ventilation fans
Sensor cooling fans
Multimedia GPU cooling systems

Procurement Notes

Verify the specific suffix -SP indicates bulk packaging when sourcing samples or small quantities. Confirm the 40V clamp rating aligns with the target application's transient voltage requirements. Ensure the UTDFN-6 footprint matches the PCB layout constraints. Check for any export documentation requirements if shipping from restricted regions. Validate that the 600mA output current meets the load specifications.

Selection Notes

Select this part for automotive applications requiring reliable single-coil fan control without complex closed-loop feedback hardware. The UTDFN-6 package offers a small form factor for space-constrained designs. Consider the 40V clamp version if the system experiences significant load dump events. Ensure the design accommodates the humidity sensitivity level indicated in the datasheet. This model is suitable for direct battery-fed applications in 12V automotive architectures.

Part Context

This component belongs to the MLX90411 family of intelligent fan drivers. The LLD suffix denotes the UTDFN-6 package type, while BAA indicates the specific electrical characteristics and clamp voltage. The -SP suffix typically refers to sample or small-bulk packaging. The family is designed to replace discrete solutions, reducing bill of materials and board space while improving acoustic performance and efficiency in thermal management systems.
