It integrates the switching stage for a resonant LLC half-bridge topology, delivering a regulated output through a transformer without requiring a feedback loop on the secondary side. The part is AEC-Q100 qualified and operates from a 9V to 34V supply, making it suitable for 12V and 24V vehicle electrical systems, as well as industrial battery-backed rails. Typical applications include isolated gate-drive bias supplies, auxiliary power for traction inverters, and on-board charger housekeeping rails where galvanic isolation is needed. The 9V to 34V input range covers both nominal 12V and 24V automotive buses, including cold-crank and load-dump transients within the abs-max window. The 14mA supply current is the driver's own consumption at no load — budget additional current for the transformer primary and any secondary load when sizing the upstream rail. The open-loop LLC architecture means the switching frequency is set by external resistors and the transformer's resonant tank — no secondary-side regulation loop, which simplifies the design but requires careful transformer selection for load regulation. ## Package and mounting The UCC25800AQDGNRQ1 is supplied in an 8-HVSSOP package (also referred to as 8-PowerTSSOP) with an exposed thermal pad. The surface-mount footprint is compact — 3.00 mm body width — which suits space-constrained automotive ECU layouts.","metaTitle":"UCC25800AQDGNRQ1 Automotive LLC Transformer Driver, 9V-34V","metaDescription":"Texas Instruments UCC25800AQDGNRQ1 open-loop LLC transformer driver, AEC-Q100 qualified, 9V-34V supply, -40°C to 125°C, 8-HVSSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Grade":"Automotive","Package":"Tape & Reel (TR); Cut Tape (CT)","Applications":"Transformer Driver","Mounting Type":"Surface Mount","Qualification":"AEC-Q100","Package / Case":"8-PowerTSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"14mA","Voltage - Supply":"9V ~ 34V","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"8-HVSSOP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.42","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.42000","currency":"USD"},{"qty":10,"price":"$3.96600","currency":"USD"},{"qty":25,"price":"$3.74960","currency":"USD"},{"qty":100,"price":"$3.24970","currency":"USD"},{"qty":250,"price":"$3.08304","currency":"USD"},{"qty":500,"price":"$2.76640","currency":"USD"},{"qty":1000,"price":"$2.33310","currency":"USD"},{"qty":2500,"price":"$1.33623","currency":"USD"},{"qty":5000,"price":"$1.28674","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a49db5f4d66e1484e9726f31514cb456.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to UCC25800AQDGNRQ1?","answer":"The UCC25800AQDGNRQ1 is a single-sourced part from Texas Instruments; any alternate would require a separate qualification and board layout change."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/UCC25800AQDGNRQ1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/UCC25800AQDGNRQ1 when reusing this data.
