The current limit is adjustable via an external resistor — you set the trip point to match the cable gauge or connector rating, not the other way around. When a fault trips, the Status Flag output (open-drain, active low) tells the host controller to log the event or retry the port. The switch itself is self-recovering after the fault clears. The 16-WFQFN with exposed pad (3x3 mm) is a compact footprint for space-constrained USB hubs, docking stations, or automotive USB charge ports. No end-of-life notification, no last-time-buy window to track. For new designs this means standard distribution availability with no forced redesign horizon.","metaTitle":"TI TPS2547RTER USB Power Switch, 3A, 16-WQFN","metaDescription":"Texas Instruments TPS2547RTER USB high-side switch, 73 mOhm Rds(on), 3A max output, adjustable current limit, -40°C to 125°C.","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":"Status Flag","Interface":"On/Off","Input Type":"-","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","Number of Outputs":"1","Base Product Number":"TPS2547","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":"$0.4965","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fd5f413bcca59c58b148a79b7ca2c68c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2547RTER/alternatives.json"},"ai":{"faq":[{"question":"What is the maximum output current of TPS2547RTER?","answer":"The maximum continuous output current is 3 A.
