Built-in fault protection covers adjustable current limiting, over-temperature shutdown, and under-voltage lockout (UVLO). At 3 A load, the 73 mOhm typical on-resistance produces about 220 mV drop and 0.66 W dissipation inside the package. If the board layout skimps on copper, the current-limit threshold will fold back sooner than expected. The adjustable current limit lets you set the trip point below 3 A with a single resistor to ground. That's useful when the downstream load is a sensitive peripheral that cannot survive a hard short at full current — you can dial the limit down to match the cable and connector rating. For the procurement desk, that means the part is still in the normal TI distribution channel and can be quoted against a BOM quantity without obsolescence risk.","metaTitle":"TPS2544RTET USB Power Switch, 73 mOhm, 3 A, Active","metaDescription":"Texas Instruments TPS2544RTET USB power switch, 73 mOhm typical Rds(on), 3 A output, 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":"-","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":"TPS2544","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":"$1.7200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/784d2840b2aea8d2737fb2839e70e8a5.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2544RTET/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between TPS2544RTET and TPS2544RTER?","answer":"The silicon and package are identical — the RTE suffix denotes the 16-WQFN (3x3 mm) package, and the last letter (T vs R) indicates the reel option.
