The adjustable limit lets the designer set the trip point anywhere below the 1.1 A maximum, matching the cable or connector rating rather than the switch's own capability. The slew-rate-controlled turn-on (flagged in the features list) limits inrush current into capacitive loads — useful for powering USB ports or hot-swap cards where the downstream decoupling capacitance can pull the rail down on connect. ## Active lifecycle — no end-of-life clock on this BOM line","metaTitle":"Texas Instruments TPS2551DBVTG4 Power Switch, 1.1A, SOT-23-6","metaDescription":"Texas Instruments TPS2551DBVTG4 high-side power switch, 1.1A max output, 85mOhm Rds(on), adjustable current limit, SOT-23-6.","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)","Features":"Slew Rate Controlled","Interface":"On/Off","Input Type":"Non-Inverting","Output Type":"N-Channel","Switch Type":"General Purpose","Rds On (Typ)":"85mOhm","Mounting Type":"Surface Mount","Package / Case":"SOT-23-6","Voltage - Load":"2.5V ~ 6.5V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Adjustable), Over Temperature, UVLO","Number of Outputs":"1","Base Product Number":"TPS2551","Output Configuration":"High Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C~150°C(TJ)","Current - Output (Max)":"1.1A","Supplier Device Package":"SOT-23-6","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5059f815f3063e8461784b6d638e5eac.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2551DBVTG4/alternatives.json"},"ai":{"faq":[{"question":"What is the maximum current of TPS2551?","answer":"The TPS2551DBVTG4 is rated for a maximum continuous output current of 1.1 A.
