The auxiliary sense input accepts a local supply while maintaining PoE priority. ## Active lifecycle — no LTB pressure on this BOM line The part is ROHS3 compliant. For a BOM line that needs a stable, non-obsoleting PoE PD controller, this part is a clean fit for new designs and ongoing production.","metaTitle":"MAX5987AETE+T PoE PD Controller, 802.3af, 6.49 W, 16-TQFN","metaDescription":"MAX5987AETE+T is a single-channel PoE PD controller (802.3af) with integrated DC/DC switch, 8.7 V–60 V input, 6.49 W max, -40°C to 85°C.

The MAX5987B is a variant that typically adds support for 802.3at (PoE+) higher power or changes the switching frequency — the exact delta is in the datasheet. For 802.3af-only designs up to 6.49 W, the MAX5987A is the correct choice."},{"question":"Can the MAX5987AETE+T be used with 802.3at (PoE+) equipment?","answer":"The MAX5987AETE+T is specified for 802.3af (PoE) and is rated for a maximum power of 6.49 W. It does not support the higher 25.5 W power level of 802.3at. Connecting it to a PoE+ PSE will not damage the controller — the PSE will detect it as an 802.3af PD and deliver only up to the Class 0–3 power budget. For PoE+ designs, look at the MAX5987B or a dedicated 802.3at PD controller."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX5987AETET","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX5987AETET when reusing this data.
