The maximum charge current is 1.25 A, and the battery regulation voltage tops out at 4.44 V. Fault protection covers over-temperature and over-voltage conditions, which is the minimum expected for a portable-device charger in 2025. ## 1.25 A charge current — sizing the charge time For a typical 1000 mAh single-cell Li-Ion pack, 1.25 A delivers a 0.8C charge rate — fast enough for a sub-90-minute full charge from empty, but below the 1C threshold that stresses most consumer-grade cells. The charge current is constant and programmable via I²C, so the BOM can tune the rate to the cell's datasheet recommendation without a resistor change. ## 20-DSBGA — footprint and rework considerations The 20-DSBGA package (0.4 mm pitch, wafer-level) is the same footprint as the 20-UFBGA option. The small ball array saves board area but demands a solder-mask-defined pad layout and a stencil aperture that matches the ball diameter. Rework requires a hot-air profile with bottom-side preheat; the package is moisture-sensitive, so a bake cycle before reflow is mandatory if the floor life has been exceeded.","metaTitle":"TI BQ24153YFFT Li-Ion Charger IC, 1.25A I²C, 20-DSBGA","metaDescription":"Texas Instruments BQ24153YFFT single-cell Li-Ion/Polymer charger IC with I²C interface, 1.25A max charge current, 20-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)","Interface":"I²C","Mounting Type":"Surface Mount","Package / Case":"20-UFBGA, DSBGA","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":"BQ24153","Battery Pack Voltage":"4.44V (Max)","Charge Current - Max":"1.25A","Operating Temperature":"-30°C~85°C(TA)","Programmable Features":"Current, Timer","Voltage - Supply (Max)":"6V","Supplier Device Package":"20-DSBGA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.2742","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/94a1033b760a452a524155cade060711.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum charge current of BQ24153YFFT?","answer":"The maximum charge current is 1.25 A.
