It communicates over an I²C interface, letting the host system set charge parameters on the fly rather than relying on fixed resistor dividers. ## DSBGA footprint — plan the rework before you place it This part comes in a 49-bump DSBGA package measuring 2.8 mm x 2.8 mm. That is a fine-pitch BGA with no exposed leads — you need a solder-paste stencil, a reflow oven, and ideally an X-ray to verify the joints. Not a field-swap part; it goes on the board in production and stays there. The 0.5 mm pitch bumps are standard for this class, but the board layout needs to match the TI-recommended land pattern exactly to avoid head-in-pillow defects. ## Protection set covers the common failure modes Built-in fault protection covers over-temperature, over-voltage, and short-circuit conditions. That means the charger can sit on a Li-Po or Li-ion cell without an external protection IC for basic safety — the chip handles the thermal and voltage limits itself. The battery pack voltage tops out at 4.44 V, which suits standard single-cell lithium chemistries.","metaTitle":"BQ24273YFFR Battery Charger IC, 2.5A Max, I²C, DSBGA","metaDescription":"Texas Instruments BQ24273YFFR single-cell multi-chemistry charger IC with 2.5A max charge current, I²C control, 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":"I²C","Mounting Type":"Surface Mount","Package / Case":"49-UFBGA, DSBGA","Product Status":"Active","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature, Over Voltage, Short Circuit","Battery Chemistry":"Multi-Chemistry","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24273","Battery Pack Voltage":"4.44V (Max)","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":"$6.3000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2d79337c9554391af546b6cac8d91f47.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum charge current of BQ24273YFFR?","answer":"The maximum charge current is 2.5 A, and it is programmable via the I²C interface — you set the current level in the register, not with an external resistor."},{"question":"Is BQ24273YFFR a direct replacement for BQ24270?","answer":"The evidence does not list BQ24270 as a cross-reference or successor.
