The switch integrates load discharge and a status flag, so the designer gets a power-good indicator without an external comparator. ## Fault protection: adjustable current limit, over-temp, UVLO The TPS2541ARTER protects the upstream supply and the downstream load with three independent fault monitors. The current limit is adjustable via an external resistor — the designer sets the trip point between the port's rated current and the switch's 2.5 A ceiling. Over-temperature shutdown and under-voltage lockout (UVLO) prevent the switch from operating outside its safe area. The non-inverting On/Off interface lets a GPIO or a dedicated enable signal control the output. ## Temperature range and package — board-fit details","metaTitle":"TI TPS2541ARTER USB Power Switch, 73 mOhm, 2.5 A, WFQFN-16","metaDescription":"Texas Instruments TPS2541ARTER USB high-side switch, 73 mOhm Rds(on), 2.5 A max output, adjustable current limit, -40°C to 125°C junction.","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)","Features":"Load Discharge, Status Flag","Interface":"On/Off","Input Type":"Non-Inverting","Output Type":"N-Channel","Switch Type":"USB Switch","Rds On (Typ)":"73mOhm","Mounting Type":"Surface Mount","Package / Case":"16-WFQFN Exposed Pad","Product Status":"Active","Voltage - Load":"4.5V ~ 5.5V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Adjustable), Over Temperature, UVLO","Number of Outputs":"1","Base Product Number":"TPS2541","Output Configuration":"High Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C~125°C(TJ)","Current - Output (Max)":"2.5A","Supplier Device Package":"16-WQFN (3x3)","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9030","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/aa6d432bbccc4dd89cc014b977010875.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2541ARTER/alternatives.json"},"ai":{"faq":[{"question":"Does TPS2541ARTER have overcurrent protection?","answer":"Yes — the switch has adjustable current limiting, over-temperature shutdown, and under-voltage lockout (UVLO).
