MLX90411LLD-BAA-043-RE

Overview

The MLX90411LLD-BAA-043-RE is an automotive-grade, low-noise single-coil fan driver IC from Melexis. It integrates a high-sensitivity Hall effect sensor and power stage for direct motor control. The device supports supply voltages from 3V to 28V with a maximum output current of 600mA. It features integrated 40V power clamping to handle inductive kickback without external TVS diodes. Packaged in a compact UTDFN-6 (2.5x2mm) surface-mount format, it operates within a temperature range of -40°C to 150°C and holds AEC-Q100 qualification.

Feature Summary

Integrated high-sensitivity Hall effect sensor for precise commutation
Adaptive commutation control for low acoustic noise and high efficiency
Built-in 40V power clamp for robust protection against back EMF
Configurable open-loop and closed-loop speed control via I2C

Applications

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

Procurement Notes

Verify the specific suffix 'BAA-043' confirms the 40V clamp rating and 600mA current limit. Ensure the UTDFN-6 package matches the PCB footprint. Confirm AEC-Q100 compliance is required for the target automotive application. Check for any export restrictions or additional documentation needed for shipment.

Selection Notes

Select this part for applications requiring a compact, automotive-rated solution for small DC fans. The 40V clamp is suitable for 12V battery systems with load dump conditions. Choose this over consumer versions if AEC-Q100 certification and extended temperature ranges are mandatory. Consider the SOT-23-6 variant if a different package profile is preferred.

Part Context

This component belongs to the MLX90411 family of intelligent fan drivers. It is specifically the automotive-grade version utilizing the LLD package code for the UTDFN-6 form factor. The series is designed to replace discrete solutions by integrating sensing, logic, and power stages into a single chip.

Replacement Considerations

MLX90411KZE-BAA-043-RE is a consumer-grade alternative in a SOT-23-6 package. MLX90411LZE-BAA-043-SP is another automotive option in SOT-23-6. Verify pinout compatibility and thermal performance when substituting between UTDFN-6 and SOT-23-6 packages.
