The charger integrates over-temperature and short-circuit fault protection, reducing the need for external supervisory components on the power path. The 10 V maximum supply voltage gives enough headroom for a 5 V USB bus or a 9 V wall adapter without an external pre-regulator. ## Active production — no end-of-life concern For current BOM positions this means zero lifecycle risk — no need to qualify a second source or stockpile. ## Package and supply rail compatibility Surface-mount in a 24-VFQFN with exposed pad — the pad is the primary thermal path. The USB interface is the control bus. Single-cell operation means the battery pack voltage is 3.7 V nominal.","metaTitle":"BQ24166RGET Texas Instruments Li-Ion Charger IC","metaDescription":"Texas Instruments BQ24166RGET single-cell Li-Ion battery charger IC with USB interface, 2.5 A max charge current, over-temp & short-circuit protection.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Interface":"USB","Mounting Type":"Surface Mount","Package / Case":"24-VFQFN Exposed Pad","Product Status":"Active","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature, Short Circuit","Battery Chemistry":"Lithium Ion","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24166","Battery Pack Voltage":"3.7V","Charge Current - Max":"2.5A","Operating Temperature":"-40°C~85°C(TA)","Programmable Features":"-","Voltage - Supply (Max)":"10V","Supplier Device Package":"24-VQFN (4x4)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.6700","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2bbd415d200f67d1d49ab5bb9ab994ae.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does BQ24166RGET support USB charging?","answer":"Yes, the interface is USB.
