It integrates adjustable current limiting, over-temperature protection, and undervoltage lockout (UVLO), making it a self-contained load switch for USB ports, peripheral power rails, and general-purpose 2.5 V to 6.5 V distribution. This means TI will continue to support existing production for a period, but the part is not intended for new-design wins. ## Adjustable current limit — no external sense resistor The current limit is adjustable via a single external resistor, which sets the threshold between the switch's internal current-sense amplifier and the 1.1 A maximum. The slew-rate controlled turn-on (listed as a feature) reduces inrush current on capacitive loads, which is useful when the switch powers a bank of decoupling capacitors at a USB port or a sensor module.","metaTitle":"TPS2551DRVT power-distribution switch, 1.1 A, NRND","metaDescription":"Texas Instruments TPS2551DRVT high-side power switch, 1.1 A output, 100 mOhm Rds(on), adjustable current limit, 6-WSON package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"Slew Rate Controlled","Interface":"On/Off","Input Type":"Non-Inverting","Output Type":"N-Channel","Switch Type":"General Purpose","Rds On (Typ)":"100mOhm","Mounting Type":"Surface Mount","Package / Case":"6-WDFN Exposed Pad","Product Status":"Not For New Designs","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":"6-WSON (2x2)","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.3900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/05beed4c75174678adf15fb2981cec78.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2551DRVT/alternatives.json"},"ai":{"faq":[{"question":"What is the current limit of the TPS2551DRVT?","answer":"The maximum continuous output current is 1.1 A.
