It supports multi-chemistry cells including Li-ion and Li-polymer, with a maximum battery pack voltage of 4.44V. Integrated fault protection covers over-temperature, over-voltage, and short-circuit conditions, reducing the need for external supervisory circuitry. ## I²C programmability and system integration The I²C interface allows the host microcontroller to set charge current, termination threshold, and timer values dynamically during operation. Supply voltage range extends to 10V max, accommodating standard USB and 5V wall adapter inputs without an external pre-regulator. ## 49-DSBGA footprint and rework considerations Surface-mount assembly with Tape & Reel (TR) delivery; the small pitch requires a solder mask defined pad layout per TI's application note.","metaTitle":"BQ24273YFFT TI battery charger, I²C, 2.5A, 49-DSBGA","metaDescription":"Texas Instruments BQ24273YFFT single-cell battery charger with I²C interface, 2.5A max charge current, fault protection. 49-DSBGA package, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR)","Interface":"I²C","Mounting Type":"Surface Mount","Package / Case":"49-UFBGA, DSBGA","Product Status":"Active","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature, Over Voltage, Short Circuit","Battery Chemistry":"Multi-Chemistry","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24273","Battery Pack Voltage":"4.44V (Max)","Charge Current - Max":"2.5A","Operating Temperature":"-40°C~85°C(TA)","Programmable Features":"-","Voltage - Supply (Max)":"10V","Supplier Device Package":"49-DSBGA (2.8x2.8)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.8298","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2d79337c9554391af546b6cac8d91f47.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BQ24273YFFT compatible with lithium polymer batteries?","answer":"Yes, the charger supports multi-chemistry cells including Li-ion and Li-polymer, with a programmable maximum battery pack voltage of 4.44V."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ24273YFFT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ24273YFFT when reusing this data.
