It sits between a 4.4V to 18V supply rail and a load rated up to 5A, acting as a resettable circuit breaker with a built-in charge pump and power FET. When a fault clears, the auto-retry function reconnects the load automatically — no manual reset or power cycle needed. That is handy in remote or inaccessible equipment where a hard latch-off would mean a site visit.","metaTitle":"TCKE805NA,RF Electronic Fuse, 4.4V-18V Input, 5A Output","metaDescription":"TCKE805NA,RF eFuse IC with auto retry, 4.4V to 18V input, 5A output, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Electronic Fuse","Mounting Type":"Surface Mount","Package / Case":"10-WFDFN Exposed Pad","Voltage - Input":"4.4V ~ 18V","lifecycle_stage":"eol_hot","Current - Output":"5A","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"10-WSONB (3x3)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.56","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.56000","currency":"USD"},{"qty":10,"price":"$1.40400","currency":"USD"},{"qty":25,"price":"$1.32480","currency":"USD"},{"qty":100,"price":"$1.12890","currency":"USD"},{"qty":250,"price":"$1.06000","currency":"USD"},{"qty":500,"price":"$0.92750","currency":"USD"},{"qty":1000,"price":"$0.76850","currency":"USD"},{"qty":4000,"price":"$0.75000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/4dcf7cec510630519cc6b87360a2084b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does TCKE805NA,RF support auto retry and what triggers it?","answer":"Yes, it supports auto retry.
