Overview
The MLX90411KLD-BAA-049-RE is a low-noise, fully integrated single-coil fan driver from Melexis. It features an on-chip high-sensitivity Hall effect sensor for commutation and supports supply voltages of 5V, 12V, 24V, and 32V. The device provides a maximum motor current of 960mA and includes an integrated 40V power clamp to handle back-EMF without external protection components. It operates within a temperature range of -40°C to 150°C and is housed in a compact UTDFN-6 package.
Feature Summary
- Fully integrated single-coil fan driver with built-in high-sensitivity Hall effect sensor
- Integrated 40V power clamp for robust back-EMF handling
- Supports both open-loop and closed-loop speed control modes
- Configurable via I2C interface with onboard EEPROM storage
Applications
- Consumer electronics cooling fans
- Household appliance blowers
- Industrial pump applications
- Portable lithium-ion powered devices
Procurement Notes
Verify the specific suffix 'BAA' against the official datasheet to confirm the exact electrical parameters and pinout configuration. Check the component status as it may be marked as Not Recommended for New Designs (NRND). Ensure compatibility with existing PCB layouts due to the UTDFN-6 package dimensions.
Selection Notes
Select this part when a compact solution for single-coil fans is required. The 40V clamp version is suitable for 24V or 32V systems. Consider the 960mA output capability for higher power loads up to 15W. Verify if the UTDFN-6 package fits the mechanical constraints compared to SOT alternatives.
Part Context
This component belongs to the MLX90411 series, designed for consumer-grade thermal management. It integrates sensing and driving functions into a small footprint. The KLD suffix indicates the UTDFN-6 package type. The series offers various current ratings and voltage clamps to suit different fan power requirements.
Replacement Considerations
Check for direct substitutes within the MLX90411 family with different current ratings or package types. Verify if older revisions are available. No other specific substitute part numbers are confirmed in public documentation.
