The internal switch is included, so you just add the external N-channel FET and a few passives. Typical applications include redundant power supplies, automotive systems, portable battery gear, and computer systems where you need low-loss power path steering and reverse-input protection. The 7A output current rating is the continuous limit through the internal switch — size your external MOSFET and PCB copper pour accordingly, especially with the exposed pad package. The 4V to 40V supply range covers common rails like 5V, 12V, 24V, and even 48V telecom supplies, but watch the 40V absolute maximum; a 48V nominal rail with transients could exceed it. The 150 µA quiescent current is low enough for battery-backed systems where every microamp counts. The 300 ns turn-off delay is fast enough to prevent reverse current during supply switchover or fault events in most redundant architectures. It's comfortable in outdoor telecom cabinets, factory floor enclosures, and automotive passenger compartments (though not AEC-Q100 qualified per the evidence). The storage temperature range is wider, but the operating limit is what governs derating for self-heating at full load.","metaTitle":"LTC4376IDHD#PBF Current Sharing Controller, 7A, 4-40V","metaDescription":"LTC4376IDHD#PBF is an active N-channel Current Sharing Controller from Analog Devices. 7A max output, 4V-40V supply, 150 µA quiescent current, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":[],"specifications":{"Type":"Current Sharing Controller","Package":"Tube","FET Type":"N-Channel","Applications":"Automotive, Portable Battery, Redundant Power Supplies, Computer Systems","Mounting Type":"Surface Mount","Package / Case":"16-WFDFN Exposed Pad","lifecycle_stage":"eol_hot","Current - Supply":"150 µA","Delay Time - OFF":"300 ns","Voltage - Supply":"4V ~ 40V","Internal Switch(s)":"Yes","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C ~ 85°C","Current - Output (Max)":"7A","Supplier Device Package":"16-DFN (5x4)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$16.84896","priceTiers":[{"qty":1,"price":"$16.84896","currency":"USD"},{"qty":10,"price":"$16.06428","currency":"USD"},{"qty":30,"price":"$14.70108","currency":"USD"},{"qty":100,"price":"$13.51164","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/7bea4bf0cca9034efd53c1d0f8e98bfb.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LTC4376IDHD%23PBF/alternatives.json"},"ai":{"faq":[{"question":"What is the best equivalent or cross reference for LTC4376IDHD#PBF?","answer":"The closest functional equivalent is the LTC4376HDHD#PBF, which offers the same 7A output, 4V-40V supply, and 300 ns turn-off delay, but with an extended -40°C to 125°C temperature range.
