Fault protection covers over-temperature and over-voltage conditions, which is typical for a single-cell charger intended for portable equipment where the battery is close to the charging IC. ## Single-cell limitation and battery voltage This part is designed for a single lithium-ion cell only — the battery pack voltage is 3.5 V nominal, and the supply voltage can go up to 13.2 V, so it can handle USB or higher-voltage input rails. The single-cell constraint is hard; the charger does not support series-cell balancing. The BQ24261RGET carries an obsolete lifecycle status, meaning Texas Instruments has discontinued production and it is no longer available through the factory or distributors in new volumes.","metaTitle":"BQ24261RGET single-cell Li-ion charger, I²C, 3A, 24-VFQFN","metaDescription":"Texas Instruments BQ24261RGET single-cell Li-ion battery charger with I²C interface, 3A max charge current, 24-VFQFN 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":"24-VFQFN Exposed Pad","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":"24-VQFN (4x4)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.5300","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fb270a2c480daf4c50857a7835554454.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does BQ24261RGET support I2C communication?","answer":"Yes, the BQ24261RGET uses an I²C interface for programmable charge-current control.
