It integrates the switching FET and current-sense resistor internally, so the BOM stays tight — no external MOSFET or sense resistor to size and route. The 32 V to 60 V supply range covers the 48 V nominal PoE rail with headroom for cable drop and transient events on the midspan or switch backplane. ## Active lifecycle and compliance posture RoHS3 compliant (2011/65/EU + 2015/863), with no exemptions that complicate EU market entry. Quiescent supply current is 1 mA typical — negligible in a multi-port switch but worth noting for battery-backed or energy-harvesting PSE applications where every milliwatt counts.","metaTitle":"MAX5922AEUI+ PSE Controller, 802.3af, 15.4 W, 28-TSSOP","metaDescription":"Analog Devices MAX5922AEUI+ single-channel PoE PSE controller, IEEE 802.3af compliant, 15.4 W max, internal switch, 28-TSSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Controller (PSE)","Package":"Tube","Standards":"802.3af (PoE)","Power - Max":"15.4 W","Mounting Type":"Surface Mount","Package / Case":"28-TSSOP (0.173\\\", 4.40mm Width)","Auxiliary Sense":"No","lifecycle_stage":"eol_hot","Current - Supply":"1mA","Voltage - Supply":"32V ~ 60V","Internal Switch(s)":"Yes","Number of Channels":"1","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"28-TSSOP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$13.21","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$13.21000","currency":"USD"},{"qty":10,"price":"$12.14400","currency":"USD"},{"qty":25,"price":"$11.64080","currency":"USD"},{"qty":100,"price":"$10.25640","currency":"USD"},{"qty":250,"price":"$9.75308","currency":"USD"},{"qty":500,"price":"$9.12384","currency":"USD"},{"qty":1000,"price":"$8.36876","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/9b6d4ed367acbeda84743cc25f1d1cc4.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX5922AEUI","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX5922AEUI when reusing this data.
