It delivers a constant charge current up to 1.25 A max and regulates the battery pack voltage to 4.44 V max. ## Package and footprint realities Surface-mount assembly uses the 20-UFBGA, DSBGA package. The small footprint saves board area but makes manual rework difficult. The BQ24151YFFT carries an Obsolete lifecycle status from Texas Instruments. Buyers holding a BOM line for this code will need to source through independent distribution or the surplus market.","metaTitle":"BQ24151YFFT single-cell Li-ion charger, I²C, 1.25 A, DSBGA","metaDescription":"TI BQ24151YFFT single-cell Li-ion/Polymer charger with I²C interface, 1.25 A max charge current, over-voltage/temp protection.","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); Cut Tape (CT)","Interface":"I²C","Mounting Type":"Surface Mount","Package / Case":"20-UFBGA, DSBGA","Product Status":"Obsolete","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature, Over Voltage","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"Constant","Base Product Number":"BQ24151","Battery Pack Voltage":"4.44V (Max)","Charge Current - Max":"1.25A","Operating Temperature":"-40°C~85°C(TA)","Programmable Features":"Current, Timer, Voltage","Voltage - Supply (Max)":"6V","Supplier Device Package":"20-DSBGA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.3500","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://www.ti.com/general/docs/suppproductinfo.tsp?distId=10&gotoUrl=https%3A%2F%2Fwww.ti.com%2Flit%2Fgpn%2Fbq24150","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between BQ24151 and BQ24151YFFT?","answer":"The BQ24151 is the base product number; the BQ24151YFFT is a specific variant in the 20-DSBGA package (YFF suffix indicates the DSBGA package code). The electrical specifications — I²C interface, 1.25 A charge current, 4.44 V battery regulation — are identical across the base part.
