It accepts input voltages up to 13.5 V, covering USB and common adapter rails without a separate pre-regulator. Integrated fault protection — over-current, over-temperature, and over-voltage — reduces external monitoring components and simplifies the BOM for space-constrained portable designs. ## I²C programmability and charge-profile flexibility The I²C interface allows a host MCU to adjust the charge current and battery regulation voltage dynamically, enabling adaptive charging profiles for different cell capacities or temperature conditions. The charge current is constant and programmable, so the system can trade charge time against thermal budget. This makes it suitable for both new design-ins and ongoing volume production without supply-chain disruption.","metaTitle":"BQ25619RTWR I²C 1-Cell Li-Ion Charger, 1.5 A Max, 24-WQFN","metaDescription":"TI BQ25619RTWR 1-cell Li-Ion/Li-Pol charger with I²C interface, 1.5 A max charge current, 13.5 V max input, over-current/over-voltage/over-temp 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":"I²C","Mounting Type":"Surface Mount","Package / Case":"24-WFQFN Exposed Pad","Product Status":"Active","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Current, Over Temperature, Over Voltage","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"Constant - Programmable","Base Product Number":"BQ25619","Battery Pack Voltage":"4.2V","Charge Current - Max":"1.5A","Operating Temperature":"-40°C~85°C(TA)","Programmable Features":"Current","Voltage - Supply (Max)":"13.5V","Supplier Device Package":"24-WQFN (4x4)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.1300","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/045f9bdd54a19b57831bbbf71a44a051.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum charge current for the BQ25619RTWR?","answer":"The maximum charge current is 1.5 A, programmable via the I²C interface.
