It uses an I²C interface to set the charge current and the maximum battery pack voltage of 4.44 V, making it a fit for portable devices where the host microcontroller manages the charge profile. ## Constant-current charging and fault protection Yes, the BQ24187YFFR supports constant-current charging — the charge current is programmable via I²C, with a maximum of 2 A. The IC also includes over-temperature and over-voltage fault protection, covering the two most common failure modes in a single-cell Li-Ion charging path. ## Obsolete — sourcing through independent distribution The BQ24187YFFR is listed as obsolete by Texas Instruments. For existing BOM lines, last-time-buy inventory is exhausted through the factory channel; remaining stock is held by independent distributors and surplus brokers. ## 36-DSBGA package — layout and rework notes The fine-pitch BGA requires a solder stencil with small apertures and a reflow profile matched to the 0.4 mm ball pitch. For rework, a hot-air nozzle with a matching footprint and pre-bake per J-STD-033 are recommended.","metaTitle":"BQ24187YFFR Li-Ion Charger IC, 2A I²C, 36-DSBGA","metaDescription":"Texas Instruments BQ24187YFFR single-cell Li-Ion charger, 2A max charge current, I²C interface, 36-DSBGA.","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, Over Voltage","Battery Chemistry":"Lithium Ion","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24187","Battery Pack Voltage":"4.44V (Max)","Charge Current - Max":"2A","Operating Temperature":"-40°C ~ 85°C (TA)","Programmable Features":"Current","Voltage - Supply (Max)":"6V","Supplier Device Package":"36-DSBGA (2.63x2.46)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.2800","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/339093cd2d0c6a472882df52e8a7c3ea.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy BQ24187YFFR and how do I get a price?","answer":"The BQ24187YFFR is obsolete and no longer available through the factory channel.
