MLX90411LLD-BAA-043-SP

Overview

The MLX90411LLD-BAA-043-SP is an automotive-grade, low-noise single-coil fan driver IC from Melexis. It integrates a high-sensitivity Hall effect sensor and power stage in a compact UTDFN-6 package. The device supports supply voltages from 3V to 28V with a maximum output current of 600mA. It features integrated 40V power clamping for load dump protection and offers adaptive commutation for efficiency and noise reduction. Designed for -40°C to 150°C operation, it includes programmable speed control via I²C and EEPROM configuration.

Feature Summary

Integrated high-sensitivity Hall effect sensor for precise rotor position detection
Adaptive commutation control optimizing efficiency and minimizing acoustic noise across the full speed range
Built-in 40V power clamp capability to handle transient voltage spikes without external components
Programmable dynamic PI settings supporting both open-loop and closed-loop speed control modes

Applications

Automotive LED headlight cooling fans
Vehicle seat ventilation systems
Sensor cooling applications
Multimedia GPU thermal management
Truck battery-powered fan systems

Procurement Notes

This component carries the NRND (Not Recommended for New Designs) status, indicating it is not suitable for new product development due to potential discontinuation or minimum order quantity restrictions. Verify end-of-life notifications and availability constraints before finalizing designs. Ensure compliance with AEC-Q100 standards and moisture sensitivity level requirements during storage and handling procedures.

Selection Notes

Select this part for automotive environments requiring robust thermal performance up to 150°C junction temperature. The UTDFN-6 package suits space-constrained PCB layouts. Choose the 40V clamp variant specifically for direct 12V/24V battery connections facing load dump conditions. Confirm that the 600mA current limit aligns with the specific fan coil requirements and verify I²C interface compatibility with the host controller.

Part Context

Part of the MLX90411 family, which includes consumer and automotive variants. This specific suffix denotes the automotive grade with AEC-Q100 certification and the UTDFN-6 package type. It complements other Melexis solutions like the MLX90412 for dual-coil applications or MLX90421 for position sensing within vehicle thermal management architectures.
