The maximum on-resistance of 80 mOhm sets the conduction loss floor. ## Fault protection set — adjustable current limit, OTP, UVLO The TPS2505B1RGWR includes adjustable current limiting, over-temperature protection, and undervoltage lockout. The current limit is set with an external resistor, allowing the designer to tailor the trip point per port rather than relying on a fixed threshold. Over-temperature protection shuts down the switch if the die exceeds the safe junction temperature, and UVLO prevents the switch from turning on when the input supply is too low to support the load.","metaTitle":"TPS2505B1RGWR USB Switch, 3 Outputs, 80 mOhm, Active","metaDescription":"Texas Instruments TPS2505B1RGWR USB power switch with boost converter, 3 outputs, 80 mOhm max Rds(on), -40°C to 125°C, 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":"Boost Converter, Status Flag","Interface":"Logic","Input Type":"Non-Inverting","Output Type":"N/P-Channel","Switch Type":"USB Switch","Rds On (Typ)":"80mOhm (Max)","Mounting Type":"Surface Mount","Package / Case":"20-VQFN Exposed Pad","Product Status":"Active","Voltage - Load":"1.8V ~ 5.25V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Adjustable), Over Temperature, UVLO","Number of Outputs":"3","Base Product Number":"TPS2505","Output Configuration":"High Side or Low Side","Ratio - Input:Output":"1:3","Operating Temperature":"-40°C~125°C(TJ)","Current - Output (Max)":"1.1A","Supplier Device Package":"20-VQFN (5x5)","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.2100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3f196d72cade1b2f80fd4cbdc3188065.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2505B1RGWR/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between TPS2505B1RGWR and TPS2505B1RGER?","answer":"The silicon and electrical specifications are identical — the suffix indicates the shipping medium, not a functional change."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS2505B1RGWR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS2505B1RGWR when reusing this data.
