The adjustable current limit lets you set the trip threshold to match the downstream USB connector or cable rating, reducing the need for a separate current-sense resistor or polyfuse. The single output is configured as a high-side switch with a 1:1 input-to-output ratio. No external Vcc supply is required for the switch control logic — the part is self-powered from the load rail.","metaTitle":"TI TPS2543RTER USB Power Switch, 73mOhm, 3A, Active","metaDescription":"Texas Instruments TPS2543RTER USB power switch with 73 mOhm Rds(on), 3A output, adjustable current limiting, -40°C to 125°C range.","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":"-","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":"TPS2543","Output Configuration":"High Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C~125°C(TJ)","Current - Output (Max)":"3A","Supplier Device Package":"16-WQFN (3x3)","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.3600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/47628e93299879a059aa41670e065cf5.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2543RTER/alternatives.json"},"ai":{"faq":[{"question":"What is the recommended operating conditions for TPS2543RTER?","answer":"No external Vcc supply is needed — the switch is powered from the load rail."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS2543RTER","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS2543RTER when reusing this data.
