MLX90411LLD-BAA-029-RE

Overview

The MLX90411LLD-BAA-029-RE is an automotive-grade, fully integrated single-coil fan driver IC from Melexis. It features a built-in high-sensitivity Hall effect sensor and supports supply voltages from 3.2V to 32V with a maximum output current of 800mA. The device includes an integrated 20V power clamp for back-EMF protection. It operates within a junction temperature range of -40°C to 150°C and is housed in a compact 6-UTDFN (2.5x2mm) package. This component is AEC-Q100 qualified for automotive reliability.

Feature Summary

Fully integrated single-coil fan driver with embedded Hall sensor
Integrated 20V power clamp for transient voltage suppression
Supports both open-loop and closed-loop speed control via I2C programming
Adaptive commutation for low acoustic noise and high efficiency

Applications

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

Procurement Notes

Verify the specific suffix BAA-029-RE against the official Melexis datasheet to confirm the 20V clamp rating and 800mA current limit. Ensure the 6-UTDFN footprint matches the PCB layout. Confirm AEC-Q100 qualification status for the target automotive application environment.

Selection Notes

Select this part for applications requiring a compact, automotive-qualified solution for single-coil fans under 7W. The 20V clamp is suitable for 5V regulated systems. For higher voltage transients or 12V direct battery connections, consider the 40V variant. Verify that the required current does not exceed 800mA.

Part Context

This component belongs to the MLX90411 family of intelligent fan drivers. The LLD suffix indicates the 6-UTDFN package type, while the RE suffix denotes reel packaging. It is designed to replace discrete solutions by integrating control, power stages, and sensing into a single small form factor.

Replacement Considerations

MLX90411LLD-BAA-046-SP: Offers a 40V clamp instead of 20V. MLX90411LLD-BAA-023-RE: Similar package but verify current limits. Check pinout compatibility before substitution.
