Overview
The MLX90411LZE-BAA-026-RE is an automotive-grade, single-coil fan driver IC from Melexis. It integrates a high-sensitivity Hall effect sensor with full control and power stages. The device supports open-loop speed control and features integrated power clamping for 20V applications. It provides a maximum motor current of 660mA and operates within a supply voltage range of 3.2V to 32V. Designed for robust thermal management in vehicles, it includes programmable protection against overvoltage, overcurrent, and overheating conditions.
Feature Summary
- Integrated high-sensitivity Hall effect sensor for precise commutation
- Adaptive commutation control for low acoustic noise and high efficiency
- Programmable I2C interface with on-board EEPROM configuration
- Comprehensive protection including LRP, TSD, OVP, and OCP
Applications
- LED headlight cooling fans
- Seat ventilation fans
- Sensor cooling fans
- Multimedia GPU cooling fans
Procurement Notes
Verify the specific suffix BAA-026-RE against official Melexis documentation to confirm the exact electrical parameters and packaging details. Ensure compatibility with the target vehicle's voltage architecture and thermal requirements before integration. Cross-reference the AEC-Q100 certification status for the specific revision.
Selection Notes
Select this component for automotive thermal management systems requiring reliable single-coil fan control. The 20V clamp version is suitable for 5V regulated power supplies. Consider the 660mA current limit when sizing for specific fan loads. The UTDFN package offers a compact footprint for space-constrained designs.
Part Context
This part belongs to the MLX90411 series, designed for low-noise fan and pump driving in automotive environments. It distinguishes itself through integrated sensing and drive capabilities, reducing external component count. The LZE suffix indicates the specific pinout and package type used in this configuration.
Replacement Considerations
Consult official substitution lists for direct equivalents. Generic replacements may lack the integrated Hall sensor or specific automotive certifications required for these applications.
