Turn-on delay is 1.4 µs and turn-off delay is 450 ns, fast enough to prevent reverse current during supply switchover in redundant power architectures. ## External FET required — no internal switch The LM74700QDBVRQ1 does not include an internal FET; it drives an external N-channel MOSFET. The gate drive is rated for up to 5A output current, sized for the external FET's gate charge. The 1:1 input-to-output ratio means one controller per ORing channel. ## SOT-23-6 package and mounting Housed in a 6-pin SOT-23-6 package (supplier device package SOT-23-6), surface-mount only. The compact footprint suits space-constrained ECU boards. The base product number is LM74700.","metaTitle":"TI LM74700QDBVRQ1 N+1 ORing Controller, AEC-Q100, SOT-23-6","metaDescription":"Texas Instruments LM74700QDBVRQ1 N+1 ORing controller, AEC-Q100 qualified, 3.2V–65V supply, 1.4 µs turn-on delay, SOT-23-6.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Type":"N+1 ORing Controller","Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","FET Type":"N-Channel","Applications":"Automotive","Mounting Type":"Surface Mount","Package / Case":"SOT-23-6","Product Status":"Active","Delay Time - ON":"1.4 µs","lifecycle_stage":"eol_hot","Delay Time - OFF":"450 ns","Voltage - Supply":"3.2V ~ 65V","Internal Switch(s)":"No","Base Product Number":"LM74700","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C~125°C(TJ)","Current - Output (Max)":"5A","Supplier Device Package":"SOT-23-6"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.44591","priceTiers":[{"qty":1,"price":"$1.44591","currency":"USD"},{"qty":10,"price":"$1.29866","currency":"USD"},{"qty":30,"price":"$1.19487","currency":"USD"},{"qty":100,"price":"$1.08160","currency":"USD"},{"qty":500,"price":"$1.05525","currency":"USD"},{"qty":1000,"price":"$1.03826","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/f1272f02989ea02f6e3797dd7978bcab.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM74700QDBVRQ1/alternatives.json"},"ai":{"faq":[{"question":"Does LM74700QDBVRQ1 have an internal FET?","answer":"No. The LM74700QDBVRQ1 is a controller only and requires an external N-channel MOSFET for the ORing function."},{"question":"What is the difference between LM74700QDBVRQ1 and LM74700QDBVR?","answer":"The LM74700QDBVRQ1 is the AEC-Q100 automotive-qualified variant of the base LM74700QDBVR.
