MLX90411LLD-BAF-046-SP

Overview

The MLX90411LLD-BAF-046-SP is an automotive-grade, low-noise, fully integrated single-coil fan driver manufactured by Melexis Technologies NV. 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 utilizes a 6-UTDFN (2.5x2) package and operates within a junction temperature range of -40°C to 150°C. It includes integrated power clamping for transient voltage suppression and offers programmable protection features such as over-voltage, over-current, and thermal shutdown.

Feature Summary

Fully integrated single-coil fan driver with embedded Hall sensor
Integrated power clamp for transient voltage protection
Programmable adaptive commutation for efficiency and noise reduction
I2C interface with on-board EEPROM configuration

Applications

LED headlight cooling fans in automotive systems
Seat ventilation fans
Sensor cooling fans
Multimedia GPU cooling fans

Procurement Notes

Verify the specific suffix 'BAF' against official Melexis documentation to confirm exact electrical parameters and pinout compatibility. Ensure the component meets AEC-Q100 automotive qualification requirements for the target application environment. Confirm availability status as the base model may be marked as not recommended for new designs.

Selection Notes

Select this component for applications requiring robust automotive reliability and compact form factors. The UTDFN package suits space-constrained designs. Consider the integrated power clamp capabilities for direct battery connection scenarios without external TVS diodes. Evaluate the I2C configurability needs for dynamic speed control and diagnostic outputs.

Part Context

This part belongs to the MLX90411 series, designed specifically for automotive thermal management. It replaces discrete driver solutions by integrating control logic, power stage, and sensing into a single chip. The LLD suffix indicates the 6-UTDFN package variant optimized for surface-mount assembly in automotive PCBs.
