Procurement Notes
Verify the NRND status before integration, as this part is not recommended for new designs. Confirm availability through authorized distributors, noting that stock may be limited or discontinued. Ensure compliance with export restrictions if applicable to your region. Check RoHS documentation for environmental compliance requirements prior to final procurement decisions.
Selection Notes
Select this component only for legacy maintenance or specific existing designs requiring its exact specifications. Consider newer alternatives if starting a new project due to the NRND status. Evaluate the 20V rating and 1.5A current limit against load requirements. Verify compatibility with the DFN-WF-10 package footprint during PCB layout.
Part Context
This part belongs to the MLX90412 series of intelligent fan drivers by Melexis. These devices are engineered for cost-effective and compact cooling solutions in consumer appliances. The series typically integrates power stages with magnetic sensing for commutation, offering a complete solution for single-coil fan applications without external discrete components.
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 pin compatibility and electrical specifications from Melexis's current portfolio.
