The switch is controlled by a non-inverting On/Off logic input and requires no separate Vcc supply — the internal gate drive is powered from the load rail. ## Fault protection set — adjustable current limit, OTP, UVLO Built-in fault protection includes adjustable current limiting, over-temperature shutdown, and under-voltage lockout (UVLO). The current limit is set with an external resistor, allowing the designer to tailor the trip threshold to the downstream load. The slew-rate controlled turn-on reduces inrush current and minimizes bus voltage droop during hot-plug events.","metaTitle":"TPS2551QDBVRQ1 Automotive Power Switch, 85 mOhm, SOT-23-6","metaDescription":"Texas Instruments TPS2551QDBVRQ1 AEC-Q100 high-side power switch, 85 mOhm Rds(on), 1.1 A output, 2.5 V to 6.5 V.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"Automotive, AEC-Q100","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":"$3.3400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e09c5c0b06e7d4c16657528e97b4e7a9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2551QDBVRQ1/alternatives.json"},"ai":{"faq":[{"question":"Is TPS2551QDBVRQ1 obsolete or still available?","answer":"It remains available for existing production runs but is not recommended for new designs.
