Quiescent current is 27 µA — low enough to leave the controller biased on the battery line in an always-on ECU without draining the pack during key-off. The 2.5A peak gate drive turns the external FET on fast enough to hold the output within a few hundred millivolts of the input during a supply switchover. The 1:1 input-to-output ratio means one controller manages one ORing path; a typical N+1 system stacks multiple LM74720QDRRRQ1 devices, each driving its own FET, to combine paralleled supplies. ## Automotive temperature range and wettable flank package No internal switches — the controller is a gate-drive and fault-management IC; the power path is the external N-Channel FET you select based on the load current and thermal budget. This keeps the controller cool and lets you scale the FET for a 10A or 100A rail without changing the controller.","metaTitle":"LM74720QDRRRQ1 N+1 ORing Controller, 3V-65V, 27µA","metaDescription":"Texas Instruments LM74720QDRRRQ1 automotive N+1 ORing controller. 3V to 65V input, 27 µA quiescent, drives N-Channel FET, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":[],"specifications":{"Type":"N+1 ORing Controller","Package":"Tape & Reel (TR); Cut Tape (CT)","FET Type":"N-Channel","Applications":"General Purpose","Mounting Type":"Surface Mount, Wettable Flank","Package / Case":"12-WFDFN Exposed Pad","lifecycle_stage":"eol_hot","Current - Supply":"27 µA","Voltage - Supply":"3V ~ 65V","Internal Switch(s)":"No","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C ~ 125°C (TJ)","Current - Output (Max)":"2.5A","Supplier Device Package":"12-WSON (3x3)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.76","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.76000","currency":"USD"},{"qty":10,"price":"$2.47800","currency":"USD"},{"qty":25,"price":"$2.33800","currency":"USD"},{"qty":100,"price":"$1.99210","currency":"USD"},{"qty":250,"price":"$1.87052","currency":"USD"},{"qty":500,"price":"$1.63670","currency":"USD"},{"qty":1000,"price":"$1.35613","currency":"USD"},{"qty":3000,"price":"$1.26260","currency":"USD"},{"qty":6000,"price":"$1.21584","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/267ec0b33a2f76856873adb7f3ce33a5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does the LM74720QDRRRQ1 have internal switches?","answer":"No. It is a controller IC that drives an external N-Channel MOSFET — the power path is the external FET you select, not the controller itself."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM74720QDRRRQ1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM74720QDRRRQ1 when reusing this data.
