The charge current is constant and programmable via I²C, so the firmware can reduce the rate when the system is thermally constrained or running on a weak USB source. Integrated fault protection covers over-temperature, over-voltage, and short-circuit conditions. ## DSBGA package — PCB layout considerations The 49-DSBGA package measures 2.8x2.8 mm with a 0.4 mm ball pitch typical for this class. Surface-mount assembly requires a solder-paste stencil matched to the ball diameter and a reflow profile that avoids cold joints on the centre thermal pad. Not a hand-solder part — plan for a pick-and-place pass and X-ray inspection on the first build.","metaTitle":"BQ24270YFFT I²C Li-Ion Charger, 1.5 A, DSBGA-49","metaDescription":"Texas Instruments BQ24270YFFT single-cell Li-Ion battery charger with I²C interface, 1.5 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":"I²C","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":"BQ24270","Battery Pack Voltage":"3.7V","Charge Current - Max":"1.5A","Operating Temperature":"-40°C~85°C(TA)","Programmable Features":"Current","Voltage - Supply (Max)":"6V","Supplier Device Package":"49-DSBGA (2.8x2.8)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.4512","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/471892f9708ad526a7f865af9aeaa0d6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ24270YFFT/alternatives.json"},"ai":{"faq":[{"question":"Is BQ24270YFFT end of life?","answer":"No."},{"question":"How to program BQ24270YFFT via I2C?","answer":"The charge current is set by writing to the I²C control register.
