A status flag output reports fault conditions to the host controller, and the slew-rate controlled turn-on limits inrush current when a capacitive load is connected. The base product number TPS65281 covers the family; the -1RGVR suffix denotes the specific reel and package variant. That industrial temperature range suits it for outdoor telecom gear, factory automation I/O modules, and under-hood automotive USB ports where ambient temperatures can exceed 85°C.","metaTitle":"TPS65281-1RGVR USB Power Switch, 2.7A, 90mOhm, Active","metaDescription":"Texas Instruments TPS65281-1RGVR high-side USB switch, 2.7A output, 90mOhm Rds(on), adjustable current limit, -40°C to 125°C, 16-VQFN.","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)","Features":"Slew Rate Controlled, Status Flag","Interface":"On/Off","Input Type":"-","Output Type":"N-Channel","Switch Type":"USB Switch","Rds On (Typ)":"90mOhm","Mounting Type":"Surface Mount","Package / Case":"16-VQFN Exposed Pad","Product Status":"Active","Voltage - Load":"4.5V ~ 18V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Adjustable), Over Temperature, UVLO","Number of Outputs":"1","Base Product Number":"TPS65281","Output Configuration":"High Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C~125°C(TJ)","Current - Output (Max)":"2.7A","Supplier Device Package":"16-VQFN (4x4)","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.1085","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b10038fc4920f90dbabce771d21a64c5.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS65281-1RGVR/alternatives.json"},"ai":{"faq":[{"question":"What are the fault protection features of TPS65281-1RGVR?","answer":"The TPS65281-1RGVR includes adjustable current limiting (set via an external resistor), over-temperature shutdown, and under-voltage lockout (UVLO).
