The controller integrates overvoltage protection (OVP) and undervoltage lockout (UVLO), and allows the user to program the current limit threshold. It does not contain an internal pass switch — an external N-channel MOSFET handles the power path, giving the designer control over the FET's Rds(on) and thermal performance. The QFN package is surface-mount and ships in tube.","metaTitle":"LTC4281CUFD#PBF Hot Swap Controller, 2.9V-33V, 28-QFN","metaDescription":"LTC4281CUFD#PBF Analog Devices Hot Swap Controller, 2.9V to 33V supply, 3.5 mA supply current, OVP/UVLO, programmable current limit, 28-QFN, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Type":"Hot Swap Controller","Package":"Tube","Features":"OVP, UVLO","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"28-WFQFN Exposed Pad","lifecycle_stage":"eol_hot","Current - Supply":"3.5 mA","Voltage - Supply":"2.9V ~ 33V","Internal Switch(s)":"No","Number of Channels":"1","Operating Temperature":"0°C ~ 70°C","Programmable Features":"Current Limit","Supplier Device Package":"28-QFN (4x5)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$13.47","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$13.47000","currency":"USD"},{"qty":10,"price":"$12.37800","currency":"USD"},{"qty":73,"price":"$11.86493","currency":"USD"},{"qty":146,"price":"$10.45397","currency":"USD"},{"qty":292,"price":"$9.94092","currency":"USD"},{"qty":511,"price":"$9.29957","currency":"USD"},{"qty":1022,"price":"$8.52995","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a7a109d25e99de1dcec6ca67a3ef65ea.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/LTC4281CUFDPBF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/LTC4281CUFDPBF when reusing this data.
