Any stock in the independent distribution pipeline is what is left — no new production runs. The part is a single-cell Lithium Ion charger with an I²C interface for programming charge current and battery regulation voltage up to 4.44 V max. Max charge current is 2 A. The BQ24188YFFR comes in a 36-ball DSBGA measuring 2.63 x 2.46 mm. No leads, no exposed thermal pad — the die sits on the board through solder balls. This is not a hand-solder part; it needs a reflow oven or hot-air station with a fine nozzle and a profile matched to the 0.4 mm ball pitch. Surface mount only. Fault protection includes over-temperature shutdown. The charger uses constant-current / constant-voltage algorithm with programmable current via I²C. ## Sourcing an obsolete charger — what to expect Because TI has discontinued the BQ24188YFFR, procurement must source through independent distributors and brokers who hold remaining factory inventory or surplus stock. A design review is required to qualify an alternative charger IC for the same BOM position.","metaTitle":"TI BQ24188YFFR I²C Li-Ion Charger, 2A, 36-DSBGA, Obsolete","metaDescription":"Texas Instruments BQ24188YFFR single-cell Li-Ion battery charger with I²C interface, 2A max charge current, 4.44V battery regulation, -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)","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","Battery Chemistry":"Lithium Ion","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24188","Battery Pack Voltage":"4.44V (Max)","Charge Current - Max":"2A","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":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/0bda45ae8958064b335e0c8948e41f47.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ24188YFFR/alternatives.json"},"ai":{"faq":[{"question":"Is BQ24188YFFR obsolete?","answer":"Yes, Texas Instruments lists the BQ24188YFFR as obsolete.
