That 7A ceiling puts it in the high-current tier — think tablets, power banks, and industrial handhelds that need to fill a 5000 mAh+ cell in under an hour. The I²C interface means the charge current, termination voltage, and safety timers are set in firmware, not by swapping sense resistors on the board. That saves a BOM line and lets one PCB support multiple battery chemistries with a software change. ## Fault protection stack — what it catches The protection block covers over-current, over-temperature, over-voltage, and reverse-current conditions. Over-voltage on the input rail is the one that usually kills a charger first — a 5V adapter glitching to 6.5V will latch this part off before the FET sees avalanche. Reverse-current protection matters when the battery is connected and the input is absent: the charger blocks the discharge path so the battery doesn't back-feed through the switching converter. Over-temperature shutdown at the die level keeps the part from cooking itself if the thermal pad isn't soldered properly. ## Package and mounting The 42-DSBGA package measures 2.8x2.5 mm with a 0.4 mm ball pitch. That is a fine-pitch wafer-level package — the pads are the die bumps, not a substrate interposer. The solder balls are SAC305, so the peak reflow profile tops out at 260°C. Moisture sensitivity level is not listed in this record, but a DSBGA this size typically ships at MSL 1 — bake only if the bag seal is broken and the floor life is exceeded. The thermal pad is the underside of the die; the board layout needs a via-in-pad pattern under the part to pull heat into the inner copper planes. ## Supply rail and temperature range Maximum supply voltage is 6V, so a standard 5V USB adapter or a 5V regulated rail is the design target. That covers outdoor telecom gear, portable instrumentation, and battery-backed IoT gateways. ## Sourcing — active production, quoted to order That means no last-time-buy clock running, and TI is still taking factory orders for new production. The part ships in Tape & Reel (TR) format, which is the standard for the 42-DSBGA package. We source this through independent distribution channels and quote firm pricing and lead time against an RFQ for your BOM quantity.","metaTitle":"BQ25872YFFR 7A I²C Li-Ion Charger, 42-DSBGA","metaDescription":"Texas Instruments BQ25872YFFR single-cell Li-Ion/Polymer charger, 7A max charge current, I²C control, 42-DSBGA (2.8x2.5 mm), -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":"-","Package":"Tape & Reel (TR)","Interface":"I²C","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, Over Voltage, Reverse Current","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"Constant","Base Product Number":"BQ25872","Battery Pack Voltage":"-","Charge Current - Max":"7A","Operating Temperature":"-40°C~85°C(TA)","Programmable Features":"-","Voltage - Supply (Max)":"6V","Supplier Device Package":"42-DSBGA (2.8x2.5)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.0550","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/69ef9c68353f14574eb0a57b73e535a4.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum charge current of BQ25872YFFR?","answer":"The maximum charge current is 7A, constant-current mode, for a single-cell Lithium Ion or Lithium Polymer battery."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ25872YFFR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ25872YFFR when reusing this data.
