Procurement Notes
Verify component authenticity through authorized onsemi channels due to end-of-life status. Confirm package integrity and moisture sensitivity level handling procedures prior to assembly. Review the latest product change notification for manufacturing site updates. Ensure design compatibility with existing PCB footprints and thermal management requirements.
Selection Notes
Select this component for designs requiring multiple synchronized LED channels in automotive environments. Evaluate thermal dissipation needs given the 100 mA per channel output in a SOIC-16WB package. Consider the 40 V absolute maximum rating when designing against load dump conditions. Verify that the linear PWM dimming interface matches the system controller specifications.
Part Context
This part belongs to the NCV7681 family of LED drivers designed for robust automotive applications. It provides a scalable solution for multi-channel lighting control. The device integrates protection features typical of onsemi's automotive power management portfolio. It serves as a specialized interface between low-voltage logic controllers and high-power LED loads.
Replacement Considerations
The manufacturer has declared this specific part number end-of-life. Engineers must identify alternative components from the same family or compatible successors. Verify pinout compatibility and electrical parameter equivalence before substitution.
