It communicates over I²C and USB, so the host microcontroller can set charge current, termination voltage, and timer thresholds without external resistors. The 42-DSBGA (2.8×2.5 mm) footprint is the tightest constraint on this part — the 0.4 mm ball pitch means a 4-layer board with microvias is the practical minimum for fan-out. ## Input range and protection limits Built-in overcurrent and overtemperature fault protection means the charger will shut down before the inductor saturates or the die exceeds 150°C — a common failure signature on boards where the thermal pad isn't soldered down properly.","metaTitle":"BQ25898YFFR – TI MaxCharge 4A 1-Cell Li-Ion Charger","metaDescription":"Texas Instruments BQ25898YFFR MaxCharge single-cell Li-Ion/Polymer charger, 4A max charge current, I²C/USB interface, 14V input, 42-DSBGA.","metaKeywords":null},"attributes":{"series":"MaxCharge™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"MaxCharge™","Package":"Tape & Reel (TR); Cut Tape (CT)","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":"$3.8200","priceTiers":[{"qty":1,"price":"$3.82000","currency":"USD"},{"qty":10,"price":"$3.43100","currency":"USD"},{"qty":25,"price":"$3.24360","currency":"USD"},{"qty":100,"price":"$2.81110","currency":"USD"},{"qty":250,"price":"$2.66696","currency":"USD"},{"qty":500,"price":"$2.39306","currency":"USD"},{"qty":1000,"price":"$2.04000","currency":"USD"},{"qty":3000,"price":"$2.04000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/61fdf01e0a35777d519929f869388327.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ25898YFFR/alternatives.json"},"ai":{"faq":[{"question":"Can BQ25898YFFR charge a 2-cell (2S) lithium battery?","answer":"No — the BQ25898YFFR is specified for single-cell (1-cell) Li-Ion/Polymer only.
