Procurement Notes

Verify the specific suffix (+T) indicates tape-and-reel packaging when ordering. Confirm the manufacturer designation as Analog Devices Inc. or Maxim Integrated, as both entities are associated with this product line. Ensure the component meets RoHS compliance requirements if specified for your project. Cross-reference the full part number including the lead-free indicator to match exact inventory specifications.

Selection Notes

Select this component for designs requiring an integrated solution for IEEE 802.3af PoE PDs. The internal MOSFET integration reduces external component count compared to discrete solutions. Consider the 20-TSSOP package size for board space constraints. Verify that the 11V to 76V input range aligns with your system's PoE power sourcing equipment capabilities.
