Procurement Notes

Verify end-of-life status before finalizing designs, as this component is marked as discontinued by the manufacturer. Confirm availability through authorized distributors or secondary markets, noting that stock may be limited. Ensure compatibility with existing PCB footprints and verify that alternative sources provide genuine parts with intact moisture sensitivity labels to prevent handling damage during assembly.

Selection Notes

Select this component when a quad-channel solution is required for driving multiple brushed DC motors or loads. The 125mOhm on-resistance offers lower conduction losses compared to higher-resistance alternatives like the VN770 series. Consider the 9A current rating against peak load requirements. Verify that the 36V maximum supply voltage aligns with the system's electrical environment and that AEC-Q100 qualification meets specific automotive reliability mandates.

Part Context

This part belongs to the VN772KP-E series of smart power switches. It is manufactured using VIPower technology, which integrates power MOSFETs with control and protection logic on a single monolithic chip. This integration reduces board space and simplifies design compared to discrete implementations. The series is targeted at robust industrial and automotive environments requiring high reliability.
