Overview
The MLX90411KLD-BAB-049-RE is a low-noise, fully integrated single-coil fan driver IC from Melexis. It features an onboard high-sensitivity Hall effect sensor and supports supply voltages from 3.2V to 32V with a maximum output current of 960mA. The device utilizes a UTDFN-6 package (2.5x2.0x0.4mm) for surface-mount installation. Designed for consumer applications, it includes integrated power clamping and adaptive commutation control for efficient operation across various speeds.
Feature Summary
- Fully integrated single-coil fan driver with onboard high-sensitivity Hall effect sensor
- Adaptive commutation control for optimized efficiency and low acoustic noise
- Integrated power clamping for protection against back EMF without external TVS diodes
- Configurable via I2C interface with on-board EEPROM storage
Applications
- Information Technology cooling systems
- Home appliance fans and blowers
- Industrial pump and fan drives
- Portable lithium-ion powered devices up to 32V
Procurement Notes
This component carries the status NRND (Not Recommended for New Designs). Engineers should verify if this lifecycle stage impacts long-term availability or manufacturing continuity for existing projects. Official documentation should be consulted for specific export restrictions and RoHS compliance details before finalizing procurement plans.
Selection Notes
Select this part for compact consumer electronics requiring a small footprint and low noise. The UTDFN-6 package suits space-constrained designs. Ensure the application voltage aligns with the 3.2V to 32V range. Note that this specific suffix variant targets consumer-grade environments rather than automotive AEC-Q100 certified requirements.
Part Context
Part of the MLX90411 family, which offers both consumer and automotive versions. This specific model uses the KLD suffix indicating the UTDFN-6 package type. It shares core driver technology with other variants but differs in packaging and target market certification, distinguishing it from the LZE/LDD automotive series.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the NRND status, alternative sourcing may require evaluating pin-compatible drivers from other manufacturers or considering newer generations within the same product family if supported by official cross-reference lists.
