It delivers a programmable constant charge current up to 3 A maximum, targeting the 4.2 V battery pack voltage typical of Li-Ion cells. The 3 A maximum charge current sets the power-stage inductor and input capacitor sizing. At 3 A continuous, the input supply must deliver at least 6 V (the supply maximum) with headroom for the linear dropout. The I²C interface allows the host MCU to adjust the charge current dynamically — useful for thermal throttling or USB input current limiting — but requires an I²C bus pull-up and a dedicated GPIO for the charge-enable line. Because the charge current is constant-programmable rather than resistor-set, the BOM saves one precision resistor but adds a firmware dependency. The 36-DSBGA package (2.63 x 2.46 mm) demands a controlled solder-paste stencil and X-ray inspection for voiding under the bumps — not a hand-solder part. The BQ24262YFFT carries an Obsolete lifecycle status. Buyers should verify the lot date code and moisture-sensitivity level (MSL) before reflow, as DSBGA packages absorb moisture quickly and may require a pre-bake if the shelf life has been exceeded.","metaTitle":"BQ24262YFFT Li-Ion Charger IC, 3A, I²C, DSBGA-36","metaDescription":"Texas Instruments BQ24262YFFT single-cell Li-Ion battery charger with I²C interface, 3A max charge current, 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":"BQ24262","Battery Pack Voltage":"4.2V","Charge Current - Max":"3A","Operating Temperature":"-40°C~85°C(TA)","Programmable Features":"Current","Voltage - Supply (Max)":"6V","Supplier Device Package":"36-DSBGA (2.63x2.46)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.1200","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fb270a2c480daf4c50857a7835554454.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for BQ24262YFFT?","answer":"A pin-compatible alternative within the same charger family would need to be verified against the BQ24262 base product number and the 36-DSBGA footprint.
