Procurement Notes

Verify the specific suffix 'V+T' against the manufacturer's current datasheet to confirm packaging and tape-and-reel specifications. Confirm AEC-Q100 qualification status directly with Analog Devices or authorized distributors. Check for any end-of-life notices or obsolescence warnings prior to final design approval. Ensure compatibility with existing PCB footprint requirements for the TQFN-EP-16 package.

Selection Notes

Select this component when automotive-grade USB protection and integrated power switching are required. It is suitable for designs needing both signal line protection and substantial current handling up to 3A. Consider the operating temperature range and package thermal characteristics for integration into confined automotive enclosures. Verify that the USB DCP detection features align with the target charging protocol requirements.
