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. ## Package and mounting 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. Availability and pricing are confirmed per RFQ — no stock-holding claim is made here. 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,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/0bda45ae8958064b335e0c8948e41f47.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BQ24188YFFR obsolete?","answer":"Yes, Texas Instruments lists the BQ24188YFFR as obsolete.
