Its 73 mOhm typical Rds(on) sets the voltage drop and self-heating at the 2.5 A maximum continuous output — at full load the drop is roughly 180 mV, and the I²R loss is about 0.46 W. ## USB VBUS voltage range with adjustable current limit No separate Vcc/Vdd bias is required — the switch is self-powered from the load rail. The current limit is adjustable via an external resistor, which lets you set the trip point anywhere below the 2.5 A maximum. Fault protection includes overtemperature shutdown and undervoltage lockout (UVLO) that prevents the switch from turning on until the input is stable. The status flag output (open-drain, active low) signals fault conditions like overcurrent or overtemperature to the host controller.","metaTitle":"TPS2541RTER USB Power Switch, 73 mOhm, 2.5 A, 16-WQFN","metaDescription":"Texas Instruments TPS2541RTER USB high-side switch, 73 mOhm typical Rds(on), 2.5 A max output, 4.5-5.5 V supply, -40 to 125°C, active production.","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":"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/4113b82f0df35b5b519795d9a3dc5df8.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2541RTER/alternatives.json"},"ai":{"faq":[{"question":"What is the typical Rds(on) for TPS2541RTER?","answer":"The typical on-resistance is 73 mOhm.
