MLX90411LLD-BAE-046-RE

Overview

The MLX90411LLD-BAE-046-RE is an automotive-grade, low-noise, fully integrated single-coil fan driver manufactured by Melexis Technologies NV. Designed for applications requiring robust thermal management, this component features a built-in high-sensitivity Hall effect sensor and supports supply voltages ranging from 3.2V to 32V. It provides an output current capability of up to 800mA and includes integrated power clamping options. The device is housed in a compact 6-pin UTDFN package (2.5x2mm) suitable for surface mount installation.

Feature Summary

Fully integrated single-coil fan driver with built-in high-sensitivity Hall effect sensor
Adaptive commutation control for optimized efficiency across the entire speed range
Integrated power clamp protection against back-EMF voltage spikes
Configurable open-loop and closed-loop speed control via I2C interface

Applications

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

Procurement Notes

Verify the specific suffix 'BAE' against official Melexis documentation, as standard listings typically utilize 'BAA'. Confirm AEC-Q100 qualification status and operating temperature range (-40°C to 150°C). Ensure compatibility with the 6-UTDFN footprint and check for any export restrictions or moisture sensitivity level requirements before procurement.

Selection Notes

Select this component for automotive environments requiring reliable fan control with minimal acoustic noise. The integrated Hall sensor eliminates external components, while the adaptive commutation ensures high efficiency. Consider the 800mA current limit and 32V supply range when matching motor specifications. Verify that the UTDFN package dimensions fit the available PCB space constraints.

Part Context

This part belongs to the MLX90411 family of fan drivers, specifically the automotive-grade L-series variants. It complements consumer-grade K-series parts by offering extended temperature ranges and rigorous automotive certification. The LLD suffix indicates the UTDFN-6 package type, distinguishing it from SOT-23-6 packaged alternatives within the same functional family.
