The I2C bus allows the host microcontroller to set the charge current, termination threshold, and input current limit dynamically, which is useful for systems that need to throttle charging based on thermal or input power constraints. ## Integrated fault protection reduces BOM The 10V maximum supply voltage accommodates standard USB VBUS (5V) and common wall-adapter outputs with margin for transients. ## Package and thermal considerations The exposed pad should be connected to the system ground plane with multiple vias to keep junction temperature within limits at 2A charge current.","metaTitle":"BQ24272RGER Texas Instruments Battery Charger IC, 2A, I2C","metaDescription":"Texas Instruments BQ24272RGER single-cell Li-Ion charger IC with I2C interface, 2A max charge current, fault protection, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Series":"-","Interface":"I2C","Packaging":"Tape & Reel (TR)","Part Status":"Active","Manufacturer":"Texas Instruments","Mounting Type":"Surface Mount","Package / Case":"24-VFQFN Exposed Pad","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":"BQ24272","Battery Pack Voltage":"3.7V","Charge Current - Max":"2A","Operating Temperature":"-40°C ~ 85°C (TA)","Programmable Features":"-","Voltage - Supply (Max)":"10V","Supplier Device Package":"24-VQFN (4x4)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.5172","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/142184bc1d6f024f414ae7f0e5c3bcf3.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ24272RGER/alternatives.json"},"ai":{"faq":[{"question":"What is the maximum charge current of BQ24272RGER?","answer":"The BQ24272RGER supports a programmable constant charge current up to 2A for a single-cell Li-Ion battery pack.
