That current density in a 49-DSBGA package measuring 2.8x2.8 mm means the thermal path is through the board — the pad layout and copper pour directly set the junction temperature during a full-current charge cycle. Fault protection covers over-temperature and short-circuit events, so the charger can sit on the battery rail without a separate supervisor in many designs. ## Charge current and thermal budget in a DSBGA The 2.5 A ceiling is a constant-current programmable limit, which means the actual charge rate is set by a resistor or I²C — not fixed at 2.5 A. The battery pack voltage is 3.7 V nominal, so the charger regulates the float voltage for a single-cell Li-Ion stack. Package is 49-UFBGA, DSBGA with the supplier device package 49-DSBGA (2.8x2.8 mm). Surface-mount only. The 0.5 mm ball pitch demands a controlled solder-paste stencil and a 4-layer board if you need to route signals under the BGA — the inner layers carry the high-current charge path to keep the top-layer copper pour clean. ## Active production — no obsolescence watch needed The part is available in Tape & Reel (TR) or Cut Tape (CT), which covers both prototype and production reel quantities.","metaTitle":"BQ24165YFFR - Texas Instruments Li-Ion Charger IC, 2.5A","metaDescription":"Active Texas Instruments BQ24165YFFR single-cell Li-Ion charger IC. 2.5A max charge current, USB interface, -40°C to 85°C range, 49-DSBGA package.","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":"49-UFBGA, DSBGA","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":"BQ24165","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":"49-DSBGA (2.8x2.8)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.9700","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/31ac4412c7aabe3330da0de5183117ec.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BQ24165YFFR RoHS compliant?","answer":"The BQ24165YFFR is supplied in a 49-UFBGA, DSBGA package and is lead-free per Texas Instruments standard RoHS compliance for this package family.
