Overview
The MLX90411KLD-BAA-029-RE is a single-coil fan driver from Melexis, designed for consumer applications. It features an integrated high-sensitivity Hall effect sensor and supports supply voltages of 5V, 12V, 24V, and up to 32V. The device provides a maximum motor current of 960mA and includes an integrated 20V power clamp. Packaged in a compact 6-UTDFN (2.5x2mm) format, it offers low-noise operation and adaptive commutation for efficient performance in fans, blowers, or pumps with power ratings up to 15W.
Feature Summary
- Integrated high-sensitivity Hall effect sensor for precise speed control
- Adaptive commutation technology ensures high efficiency across the entire operating speed range
- Built-in 20V power clamp eliminates the need for external transient voltage suppression components
- Supports both open-loop and closed-loop speed control modes
Applications
- Information Technology cooling systems
- Home appliance fans and blowers
- Industrial pump drives
- Portable lithium-ion battery powered devices
Procurement Notes
Verify component authenticity through authorized Melexis distributors. Confirm that the specific suffix matches the required electrical parameters. Check for export restrictions if shipping from the United States. Ensure storage conditions comply with moisture sensitivity level requirements prior to soldering.
Selection Notes
Select this variant for applications requiring up to 960mA drive current with a 20V clamp. It is suitable for 5V, 12V, and 24V systems where space is limited due to the small UTDFN package. Consider the automotive version if AEC-Q100 certification is mandatory.
Part Context
This part belongs to the MLX90411 series, which integrates sensing and driving capabilities into a single chip. The KLD suffix indicates a consumer-grade device in a 6-UTDFN package. The series is optimized for low acoustic noise and vibration in single-coil motor applications.
Replacement Considerations
Publicly confirmed direct substitute part numbers are not available in the provided documentation. Verify compatibility with existing magnetic sensors and control logic before attempting cross-referencing.
