Housed in a 36-DSBGA package measuring 2.63x2.46 mm, it is a surface-mount device suited for space-constrained portable designs. ## Charge current and input voltage — sizing the power path The 3A maximum charge current sets the power delivery ceiling for a single-cell Li-ion battery — enough for a tablet or power-tool battery pack, but you will need a supply capable of sourcing that current at the input. Maximum supply voltage is 13.2V, so it accepts standard 5V USB or 9V/12V adapter inputs without an external pre-regulator, though the thermal budget in the DSBGA package will limit sustained charge current at the upper end of the input range. ## Fault protection and programmable features Built-in fault protection covers over-temperature and over-voltage conditions, reducing external component count for a robust charging solution. The I2C interface allows the host microcontroller to program the charge current in real time, enabling dynamic thermal management or input current limiting based on the adapter capability.","metaTitle":"TI BQ24261MYFFR Battery Charger IC, 3A, I2C, Obsolete","metaDescription":"Texas Instruments BQ24261MYFFR single-cell Li-ion charger IC, 3A max charge current, I2C programmable, 36-DSBGA, -40°C to 85°C.","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":"$2.9700","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d87f2bc375dd12ef35096badc7404c00.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ24261MYFFR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ24261MYFFR when reusing this data.
