It integrates the switching FET internally and delivers up to 40 W per port over a single Ethernet pair set. ## Supply range and controller overhead Operating from a 32 V to 60 V supply rail, the controller itself draws 2.5 mA typical — the overhead is negligible against the 40 W delivery budget. ## Footprint and board integration Housed in a 28-WFQFN exposed-pad package (5x5 mm, TQFN-28), the part mounts on a standard surface-mount land pattern.","metaTitle":"MAX5971BETI+ PoE+ PSE Controller, 40 W, 1-Ch, 28-TQFN","metaDescription":"Active-production Analog Devices MAX5971BETI+ single-channel PoE+ PSE controller. 40 W max, 802.3at/af, 32-60 V supply, -40 to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Type":"Controller (PSE)","Package":"Tube","Standards":"802.3at (PoE+), 802.3af (PoE)","Power - Max":"40 W","Mounting Type":"Surface Mount","Package / Case":"28-WFQFN Exposed Pad","Auxiliary Sense":"No","lifecycle_stage":"eol_hot","Current - Supply":"2.5mA","Voltage - Supply":"32V ~ 60V","Internal Switch(s)":"Yes","Number of Channels":"1","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"28-TQFN (5x5)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.16","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$11.16000","currency":"USD"},{"qty":10,"price":"$10.25300","currency":"USD"},{"qty":25,"price":"$9.82840","currency":"USD"},{"qty":100,"price":"$8.65950","currency":"USD"},{"qty":250,"price":"$8.23452","currency":"USD"},{"qty":500,"price":"$7.70328","currency":"USD"},{"qty":1000,"price":"$7.06576","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/457a73760d3d57ffb62b5bdafed5c21b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How can I check pricing and availability for MAX5971BETI+?","answer":"Submit an RFQ through the storefront for a firm quote with sourcing through independent distribution channels."},{"question":"What is the MAX5971BETI+ rated for in terms of power and standards?","answer":"It delivers up to 40 W per channel and complies with both 802.3at (PoE+) and 802.3af (PoE) standards."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX5971BETI","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX5971BETI when reusing this data.
