The controller drives an external N-channel MOSFET (no internal switch) and manages the ORing function with a 1.4 µs ON delay and 450 ns OFF delay. The fast OFF delay is critical: when the active supply drops, the controller shuts the FET in under half a microsecond to prevent reverse-current backfeed into the failed rail. ## 3.2V–65V supply range — covers 12V, 24V, and 48V automotive buses The supply voltage range of 3.2V to 65V covers the nominal 12V/24V/48V automotive rails plus load-dump transients up to 60V. The 5A maximum output current drives the gate of the external N-channel MOSFET hard enough to achieve the 1.4 µs turn-on time even with a large die FET. The 1:1 input-to-output ratio means each ORing channel passes one supply rail; in an N+1 configuration, multiple controllers share a common output bus. The SOT-23-8 (TSOT-23-8) package keeps the PCB footprint small — critical when packing redundant power paths into a compact ECU.","metaTitle":"TI LM74700QDDFRQ1 N+1 ORing Controller, AEC-Q100, 3.2V–65V","metaDescription":"Texas Instruments LM74700QDDFRQ1 N+1 ORing Controller, AEC-Q100 qualified, -40°C to 125°C, 1.4 µs ON / 450 ns OFF delay, SOT-23-8.","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-23-8","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":"TSOT-23-8"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.4100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/abd886101a549b095da56a0a420e9e89.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM74700QDDFRQ1/alternatives.json"},"ai":{"faq":[{"question":"Does LM74700QDDFRQ1 meet AEC-Q100 automotive qualification?","answer":"Yes — the series is listed as Automotive, AEC-Q100.
