Procurement Notes
This part number is marked as Not Recommended for New Designs (NRND). Verify availability through authorized distributors as stock may be limited. Confirm that the SOT-23-6 package and 600mA current rating meet project requirements before procurement. Check for potential obsolescence risks and consider alternative future-proof solutions if long-term supply is critical.
Selection Notes
Select this component for applications requiring a compact, low-noise solution for single-coil fans operating at 5V, 12V, or 24V. The SOT-23-6 package suits space-constrained designs. Ensure the load current does not exceed 600mA. The integrated clamping eliminates the need for external TVS diodes in standard voltage scenarios. Verify compatibility with existing PCB footprints and thermal constraints.
Part Context
The MLX90411 series represents Melexis' intelligent fan driver family, combining sensing and driving capabilities in a single chip. This specific variant targets the consumer market, offering a balance of performance and cost. It complements automotive-grade versions like the MLX90411L series, which feature AEC-Q100 certification and extended temperature ranges for harsher environments.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. As this part is NRND, engineers should consult Melexis technical support for recommended next-generation replacements or cross-reference tools to identify compatible devices with updated supply status.
