It integrates over-current and over-voltage fault protection, reducing the external protection component count on the board. The 56-DSBGA (3.33x2.93 mm) package fits the tight floorplan of a smartphone or power bank PCB. ## I²C programmability and protection The I²C interface lets the system host adjust charge current, termination threshold, and battery regulation voltage on the fly — useful for adaptive fast-charging profiles that trade off charge time against thermal budget. The built-in over-current and over-voltage protection catches a fault before it reaches the battery, which saves adding a separate protector IC.","metaTitle":"BQ25971YFFR I²C Battery Charger, 8A Max, 56-DSBGA","metaDescription":"Texas Instruments BQ25971YFFR single-cell multi-chemistry battery charger with I²C interface, 8A max charge current, 4.65V pack voltage","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":"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":"$3.3000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2e22d1d85699ea0852cd0b59951f346d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum charge current of BQ25971YFFR?","answer":"The BQ25971YFFR supports a maximum charge current of 8A."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ25971YFFR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ25971YFFR when reusing this data.
