It targets fast-charge applications in portable electronics, power tools, and compact medical devices where charge time drives the BOM. The I²C interface allows the system host to program charge voltage, current, and termination thresholds, and to read fault flags. ## 12V supply ceiling and 4.65V pack voltage Maximum supply voltage is 12V, so the input rail must be regulated below that — a 5V or 9V USB-C source works directly, but a 12V adapter needs a pre-regulator or OVP clamp. The battery pack voltage tops out at 4.65V, which suits 1-cell Li-ion or Li-polymer with a 4.4V or 4.45V termination ceiling, as well as LiFePO4 cells at their 3.65V float. Over-current and over-voltage fault protection are integrated, so external protection FETs can be minimal. ## 56-DSBGA — fine-pitch BGA layout considerations The 56-DSBGA package measures 3.33x2.93 mm with 0.5 mm or finer ball pitch (typical for DSBGA). This demands a 4-layer PCB minimum for fan-out, with micro-vias or via-in-pad for the inner rows. The small footprint saves board area, but the BGA reflow profile and X-ray inspection are non-negotiable for production yield. ## Active production — no EOL watch needed For production planning, this means no imminent last-time-buy risk and no forced redesign.","metaTitle":"TI BQ25970YFFR Battery Charger IC, 8A, I²C, 56-DSBGA","metaDescription":"Texas Instruments BQ25970YFFR multi-chemistry battery charger IC with 8A max charge current, I²C interface, 56-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":"56-UFBGA, DSBGA","Product Status":"Active","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Current, Over Voltage","Battery Chemistry":"Multi-Chemistry","Current - Charging":"-","Base Product Number":"BQ25970","Battery Pack Voltage":"4.65V (Max)","Charge Current - Max":"8A","Operating Temperature":"-40°C~85°C(TA)","Programmable Features":"-","Voltage - Supply (Max)":"12V","Supplier Device Package":"56-DSBGA (3.33x2.93)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.4900","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2e22d1d85699ea0852cd0b59951f346d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BQ25970YFFR compatible with 1-cell Li-ion batteries?","answer":"Yes. The BQ25970YFFR is a single-cell charger with a maximum battery pack voltage of 4.65V, which covers standard 1-cell Li-ion (4.2V), Li-ion high-voltage (4.35V/4.4V), and LiFePO4 (3.65V) chemistries. The multi-chemistry designation means the charge algorithm can be configured via I²C for the target cell type."},{"question":"Can BQ25970YFFR replace BQ25970 or BQ25970YFFT?","answer":"The BQ25970YFFR shares the same base product number BQ25970, so it is functionally identical to other BQ25970 variants. The YFFR suffix specifies the 56-DSBGA package in Tape & Reel; the YFFT suffix typically indicates a different reel quantity or tube packaging. Confirm the package code and reel dimensions against your BOM — the die and charge parameters are the same across the family."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ25970YFFR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ25970YFFR when reusing this data.
