Built-in fault protection includes over-temperature and short-circuit detection, reducing the need for external supervisory circuitry. ## 49-DSBGA footprint and rework considerations The BQ24166YFFR is supplied in a 49-UFBGA, DSBGA package (49-DSBGA, 2.8x2.8 mm body). Reworking a DSBGA by hand is possible with a hot-air station and a stencil alignment jig, but the part's small size makes optical alignment critical — a misaligned reflow can short adjacent balls. Moisture sensitivity level (MSL) should be verified per the reel label before rework; a pre-bake at 125°C for 8 hours is typical if the floor life has been exceeded. The Tape & Reel (TR) packaging is standard for volume production.","metaTitle":"TI BQ24166YFFR Li-Ion Battery Charger IC, 2.5 A","metaDescription":"Texas Instruments BQ24166YFFR single-cell Li-Ion charger IC with USB interface, 2.5 A max charge current, 10 V max supply, over-temp and short-circuit","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":"USB","Mounting Type":"Surface Mount","Package / Case":"49-UFBGA, DSBGA","Product Status":"Active","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature, Short Circuit","Battery Chemistry":"Lithium Ion","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24166","Battery Pack Voltage":"3.7V","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":"$2.9700","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2bbd415d200f67d1d49ab5bb9ab994ae.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between BQ24166 and BQ24166YFFR?","answer":"The base product number is BQ24166. The 'YFFR' suffix indicates the specific package variant — the 49-DSBGA (2.8x2.8) package and Tape & Reel packaging. Functionally, the BQ24166 die is identical across package variants; the difference is purely in the physical footprint and shipping format."},{"question":"Is BQ24166YFFR lead-free?","answer":"The BQ24166YFFR is a DSBGA package, which typically uses lead-free solder balls (SAC305 or similar)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ24166YFFR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ24166YFFR when reusing this data.
