The switch delivers up to 1.1 A continuous output current and includes adjustable current limiting, over-temperature shutdown, and undervoltage lockout (UVLO) for fault protection. The slew-rate controlled turn-on reduces inrush current on capacitive loads. ## NRND — plan for last-time-buy This means TI has flagged the part for eventual discontinuation; new designs should evaluate an alternative, and existing BOM lines should secure inventory through the last-time-buy window or source from independent distribution. For production continuity, buyers should qualify a pin-compatible high-side switch or a cross-sourced device. The SOT-23-6 package (supplier device package SOT-23-6) is a surface-mount, small-outline transistor outline with six leads. The 85 mOhm typical Rds(on) at 1.1 A results in conduction loss. Derating is necessary above 85°C ambient.","metaTitle":"TPS2551DBVT Power Distribution Switch, 1.1A, SOT-23-6, NRND","metaDescription":"Texas Instruments TPS2551DBVT high-side power switch, 2.5V-6.5V input, 1.1A output, 85mOhm Rds(on), adjustable current limit.","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)":"85mOhm","Mounting Type":"Surface Mount","Package / Case":"SOT-23-6","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":"SOT-23-6","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/TPS2551DBVT/alternatives.json"},"ai":{"faq":[{"question":"Can I use TPS2551DBVT for USB power distribution?","answer":"Yes — the 2.5 V to 6.5 V input range covers USB 2.0 (5 V) and USB 3.0 (5 V) rails, and the adjustable current limit can be set to 500 mA (USB 2.0) or 900 mA (USB 3.0).
