It delivers a programmable constant charge current up to 2.5 A max, sized for portable devices that need fast charging without a separate microcontroller PWM pin. ## Protection and temperature range Built-in fault protection covers over-temperature and over-voltage conditions, reducing the external supervisor circuitry the BOM would otherwise need. ## Package and supply rails Maximum supply input is 10 V, so a 5 V USB rail or a 9 V wall adapter fits within the absolute maximum; a 12 V rail would need a pre-regulator.","metaTitle":"BQ24161RGER Texas Instruments Li-Ion Charger, 2.5A, I²C","metaDescription":"BQ24161RGER single-cell Li-Ion battery charger from TI. 2.5A max charge current, I²C interface, -40°C to 85°C.","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)","Interface":"I²C","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, Over Voltage","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24161","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":"$2.9700","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/77833ded8e778e5bdab6222dc31031fa.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does the BQ24161RGER support 2-cell battery packs?","answer":"No, the BQ24161RGER is designed for single-cell (1S) Lithium Ion/Polymer packs with a nominal battery voltage of 3.7 V.
