The part integrates adjustable current limiting, over-temperature protection, and under-voltage lockout, so the VBUS rail gets three layers of fault coverage without external supervisory circuitry. ## 2.5 A output — covers BC 1.2 and Apple 2.4 A charging profiles The 2.5 A maximum output current supports a single USB port. The current limit is adjustable via an external resistor. The 1:1 input-to-output ratio passes the full input current to the load when enabled. The wide temp grade also simplifies qualification for automotive infotainment and telematics units that require AEC-Q100-equivalent thermal margin. ## 16-WQFN (3x3 mm) — rework and footprint considerations The 16-WQFN with exposed pad is a 3x3 mm package — small enough to fit behind a stacked USB connector on a four-layer board. Rework is feasible with hot air if the board has good solder mask between the pad and adjacent vias.","metaTitle":"Texas Instruments TPS2541ARTET USB Power Switch, 73 mOhm","metaDescription":"Texas Instruments TPS2541ARTET USB power switch with 73 mOhm typical Rds(on), 2.5 A max output, adjustable current limit, active lifecycle.","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":"$1.3393","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/aa6d432bbccc4dd89cc014b977010875.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2541ARTET/alternatives.json"},"ai":{"faq":[{"question":"What is the maximum current of TPS2541ARTET?","answer":"The maximum continuous output current is 2.5 A. The current limit is adjustable via an external resistor, so the designer can set the port budget lower — 1.5 A or 2.1 A — depending on the USB specification being targeted. The 73 mOhm typical Rds(on) ensures the voltage drop at 2.5 A stays under 200 mV."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS2541ARTET","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS2541ARTET when reusing this data.
