It manages charge current up to 3 A with a programmable constant-current profile set via the I²C interface. The device targets portable and space-constrained designs where the DSBGA package saves board area but requires careful reflow profiling and X-ray inspection for voiding under the bumps. ## Charge termination and protection set Battery pack voltage terminates at 3.5 V, and the charger integrates over-temperature and over-voltage fault protection to prevent runaway during fault conditions. The supply input accepts up to 13.2 V maximum, giving headroom for 5 V USB or 12 V wall-adapter rails without an external pre-regulator. Texas Instruments has marked the BQ24261MYFFT as obsolete. Quantities are lot-specific and confirmed at RFQ; no pin-compatible direct replacement from TI has been published.","metaTitle":"BQ24261MYFFT Texas Instruments Li-Ion Charger, 3A, I²C","metaDescription":"BQ24261MYFFT single-cell Li-Ion charger IC, 3A max charge current, I²C interface, 36-DSBGA package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","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":"36-UFBGA, DSBGA","Product Status":"Obsolete","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature, Over Voltage","Battery Chemistry":"Lithium Ion","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24261","Battery Pack Voltage":"3.5V","Charge Current - Max":"3A","Operating Temperature":"-40°C~85°C(TA)","Programmable Features":"Current","Voltage - Supply (Max)":"13.2V","Supplier Device Package":"36-DSBGA (2.63x2.46)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.3600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fb270a2c480daf4c50857a7835554454.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ24261MYFFT/alternatives.json"},"ai":{"faq":[{"question":"What interface does BQ24261MYFFT use for charge control?","answer":"The BQ24261MYFFT uses an I²C interface to program the charge current and other parameters.
