It delivers up to 3A of programmable charge current from a supply up to 13.2V, with built-in over-temperature and over-voltage fault protection. ## Obsolete — plan a replacement now The BQ24261YFFT is listed as Obsolete by the manufacturer. ## 3A charge current and 13.2V input ceiling The 3A max charge current suits fast charging of a single Li-Ion cell, typical for tablets, power banks, and portable instruments. The 13.2V maximum input voltage covers standard 5V USB adapters and 12V wall warts with margin. The I²C interface allows the host to dynamically adjust the charge current, enabling thermal throttling or input current limiting without external resistors. ## 36-DSBGA package — layout and rework notes Housed in a 36-DSBGA (2.63x2.46 mm) package, this is a fine-pitch BGA with no exposed thermal pad. The small footprint saves board space but demands careful solder-paste stencil design and a controlled reflow profile. Store the reels dry — the BGA package is moisture-sensitive and requires bake before reflow if the seal is broken.","metaTitle":"BQ24261YFFT 1-Cell Li-Ion Charger, 3A, I²C, Obsolete","metaDescription":"Texas Instruments BQ24261YFFT is a 1-cell Li-Ion battery charger with I²C interface, 3A max charge current, 13.2V max input.","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":"$105.7000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fb270a2c480daf4c50857a7835554454.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does BQ24261YFFT support 2-cell batteries?","answer":"No, the BQ24261YFFT is designed for a single Li-Ion cell only, with a battery pack voltage of 3.5V.
