It communicates over an I²C interface, allowing the host to set charge parameters and read fault status. The part integrates over-current and over-voltage protection, reducing external component count in the charging path. ## Charge current and termination voltage The 8 A charge current ceiling targets fast charging of a single-cell Li-ion or Li-polymer battery. The maximum battery pack voltage is 4.65 V — slightly above the standard 4.2 V termination, so confirm compatibility with your cell's charge-termination spec. The I²C interface lets the host adjust the charge current dynamically, which is useful for thermal management in tight enclosures. ## Package and thermal considerations for 8 A The BQ25970YFFT comes in a 56-DSBGA package measuring 3.33x2.93 mm. Surface-mount assembly requires standard BGA reflow profiles; the DSBGA is a wafer-level package with no underfill needed for most portable applications. ## Lifecycle and sourcing No official second-source or pin-compatible alternate is listed on the record.","metaTitle":"BQ25970YFFT Texas Instruments Battery Charger IC, 8A I²C","metaDescription":"Texas Instruments BQ25970YFFT single-cell battery charger IC with 8A max charge current, I²C interface, over-current/over-voltage protection. 56-DSBGA package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","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":"56-UFBGA, DSBGA","Product Status":"Active","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Current, Over Voltage","Battery Chemistry":"Multi-Chemistry","Current - Charging":"-","Base Product Number":"BQ25970","Battery Pack Voltage":"4.65V (Max)","Charge Current - Max":"8A","Operating Temperature":"-40°C~85°C(TA)","Programmable Features":"-","Voltage - Supply (Max)":"12V","Supplier Device Package":"56-DSBGA (3.33x2.93)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.9900","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2e22d1d85699ea0852cd0b59951f346d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the BQ25970YFFT maximum charge current?","answer":"The maximum charge current is 8 A.
