It packs over-current and over-voltage fault protection into a 56-DSBGA package measuring 3.33×2.93 mm, making it a dense solution for space-constrained portable electronics. ## Charge current and thermal design At 8 A max, the BQ25971YFFT targets single-cell battery packs up to 4.65 V. ## I²C control and fault monitoring The I²C interface lets the system host set charge parameters — current, voltage, termination threshold — and read fault status. Over-current and over-voltage protection are integrated, reducing external component count. The single-cell charge voltage of 4.65 V is above the typical 4.2 V Li-ion termination, so confirm the battery chemistry supports this ceiling before committing the BOM.","metaTitle":"BQ25971YFFT Texas Instruments Battery Charger IC, 8A, I²C","metaDescription":"Texas Instruments BQ25971YFFT multi-chemistry battery charger IC with 8A max charge current, I²C interface, over-current/over-voltage protection.","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":"BQ25971","Battery Pack Voltage":"4.65V","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":"$4.7573","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2e22d1d85699ea0852cd0b59951f346d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the charge current of the BQ25971YFFT?","answer":"The BQ25971YFFT has a maximum charge current of 8 A for single-cell battery packs."},{"question":"What package is the BQ25971YFFT in?","answer":"It comes in a 56-UFBGA, DSBGA package (supplier device package 56-DSBGA, 3.33×2.93 mm)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ25971YFFT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ25971YFFT when reusing this data.
