That charge current in a 42-DSBGA (2.8 x 2.5 mm) package means the PCB copper area under the package — the thermal pad and its via array — sets the real current ceiling, not the silicon alone. The I²C and USB interface gives the host control over the charge profile, termination current, and safety timers. ## 14 V input — no external pre-regulator for USB PD or 12 V adapters The 14 V supply maximum covers USB Power Delivery and common 12 V wall adapters without a front-end buck or LDO. That saves two or three passives and a regulator IC from the BOM. The I²C interface lets the system negotiate the input current limit dynamically — a 500 mA USB 2.0 port and a 3 A USB-C charger both work with the same hardware, just different register settings. ## Industrial temp range and fault protection On-chip fault protection covers over-current and over-temperature, which reduces the external sense and cutoff components the board would otherwise need. Texas Instruments lists the BQ25898DYFFR as Active. For a new-design BOM line, this removes the single-source obsolescence risk that often forces a late-stage charger swap.","metaTitle":"BQ25898DYFFR MaxCharge Li-Ion Charger, 4 A, 14 V Input","metaDescription":"Texas Instruments BQ25898DYFFR single-cell Li-Ion/Polymer charger, MaxCharge series. 4 A max charge current, 14 V input, I²C/USB 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":"MaxCharge™","Package":"Tape & Reel (TR)","Interface":"I²C, USB","Mounting Type":"Surface Mount","Package / Case":"42-UFBGA, DSBGA","Product Status":"Active","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Current, Over Temperature","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"-","Base Product Number":"BQ25898","Battery Pack Voltage":"-","Charge Current - Max":"4A","Operating Temperature":"-40°C~85°C(TA)","Programmable Features":"-","Voltage - Supply (Max)":"14V","Supplier Device Package":"42-DSBGA (2.8x2.5)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.1300","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/61fdf01e0a35777d519929f869388327.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum charge current of BQ25898DYFFR?","answer":"The maximum charge current is 4 A.
