Overview
The MLX90411KZE-BAA-043-SP is a low-noise, fully integrated single-coil fan driver manufactured by Melexis. It operates within a supply voltage range of 3 V to 28 V and supports surface mount installation in an SOT-23-6 package. The device features a maximum output current capability of 600 mA and includes an integrated high-sensitivity Hall effect sensor for commutation. Designed for consumer applications such as IT equipment, home appliances, and industrial systems, it offers open-loop speed control with programmable dynamic PI settings.
Feature Summary
- Fully integrated single-coil fan driver with built-in high-sensitivity Hall effect sensor
- Integrated power clamp providing protection against motor back-EMF
- Adaptive commutation control for optimized efficiency and low acoustic noise
- Programmable I2C interface with onboard EEPROM configuration
Applications
- Information Technology (IT) cooling fans
- Home appliance blowers and pumps
- Industrial system thermal management
Procurement Notes
Verify component status carefully as this part is marked Not Recommended for New Designs (NRND). Confirm availability constraints and potential minimum order requirements before procurement. Ensure compliance with export documentation if shipping from restricted regions. Validate that the SOT-23-6 package and 600 mA current rating align with the target design specifications.
Selection Notes
Select this component for consumer-grade applications requiring compact integration and low noise. The SOT-23-6 package suits space-constrained designs. Verify that the 28 V maximum supply voltage and 600 mA current limit meet load requirements. Consider the NRND status for long-term production viability and evaluate alternative automotive-grade versions if higher reliability or wider temperature ranges are needed.
Part Context
This component belongs to the MLX90411 series of single-coil fan drivers. It represents the consumer-grade variant, distinct from the automotive-grade MLX90411L series which holds AEC-Q100 certification. The KZE suffix indicates the specific pinout and package configuration within the broader product family designed for efficient thermal management in various electronic devices.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the NRND status, direct replacements should be evaluated based on functional equivalence and package compatibility.
