The battery pack voltage ceiling is 4.44V, covering standard 4.2V and 4.35V Li-ion cells. Fault protection includes over-temperature and over-voltage shutdown. ## NRND — plan the last-time-buy window Buyers should confirm the last-time-buy schedule and evaluate a migration path before the part enters full obsolescence. ## 30-DSBGA package and operating range The device comes in a 30-DSBGA package, a 0.4 mm pitch wafer-level chip-scale package that requires careful PCB layout for thermal and solder-joint reliability. The mounting type is surface mount, supplied on Tape & Reel.","metaTitle":"BQ24257YFFR Texas Instruments NRND 2A Single-Cell Charger","metaDescription":"BQ24257YFFR from Texas Instruments: I²C/USB-controlled single-cell charger, 2A max charge current, 4.44V battery pack voltage.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR)","Interface":"I²C, USB","Mounting Type":"Surface Mount","Package / Case":"30-UFBGA, DSBGA","Product Status":"Not For New Designs","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature, Over Voltage","Battery Chemistry":"Multi-Chemistry","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24257","Battery Pack Voltage":"4.44V (Max)","Charge Current - Max":"2A","Operating Temperature":"-40°C~85°C(TA)","Programmable Features":"Timer","Voltage - Supply (Max)":"6.5V","Supplier Device Package":"30-DSBGA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.2800","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/17ba585d526919b204848b207beec98c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How can I order BQ24257YFFR or check stock?","answer":"BQ24257YFFR is NRND — we can source it against your BOM quantity and confirm current pricing and lead time at quote.
