The exposed thermal pad (not explicitly called out here but implied by the DSBGA construction) must be connected to a copper plane for heat spreading during high-current charging.","metaTitle":"BQ24278YFFT Texas Instruments Battery Charger IC, 2.5 A","metaDescription":"Texas Instruments BQ24278YFFT single-cell Li-Ion charger IC, 2.5 A max charge current, 49-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":"-","Mounting Type":"Surface Mount","Package / Case":"49-UFBGA, DSBGA","Product Status":"Active","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature, Over Voltage, Short Circuit","Battery Chemistry":"Lithium Ion","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24278","Battery Pack Voltage":"3.7V","Charge Current - Max":"2.5A","Operating Temperature":"-40°C~85°C(TA)","Programmable Features":"-","Voltage - Supply (Max)":"10V","Supplier Device Package":"49-DSBGA (2.8x2.8)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.8298","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6fe3580da6ad526ffa9f0e225c47da8f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ24278YFFT/alternatives.json"},"ai":{"faq":[{"question":"What is the charge current of BQ24278YFFT?","answer":"The maximum charge current is 2.5 A, programmable via an external resistor.
