The switch is non-inverting, controlled by a single On/Off interface, and does not require a separate Vcc supply rail — the load voltage powers the internal gate drive. At 1.1 A output, the 85 mOhm typical on-resistance produces about 103 mW of conduction loss at 25°C junction — negligible in most designs, but the resistance rises with temperature, so budget derating above 85°C ambient. The adjustable current limit is set with an external resistor between the ILIM pin and ground, allowing the threshold to be dialled in from below 100 mA up to the 1.1 A maximum — useful for matching the switch to the load's inrush profile or to meet USB current-limit requirements. The slew-rate controlled turn-on limits inrush current from capacitive loads, reducing voltage droop on the upstream rail and preventing false resets on shared supplies. ## NRND — sourcing reality for the TPS2550DBVT","metaTitle":"TPS2550DBVT power switch, NRND, 85 mOhm, SOT-23-6","metaDescription":"Texas Instruments TPS2550DBVT high-side power switch, 1.1A output, 85 mOhm Rds(on), adjustable current limit, SOT-23-6.","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":"TPS2550","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/TPS2550DBVT/alternatives.json"},"ai":{"faq":[{"question":"Does the TPS2550DBVT have an adjustable current limit?","answer":"Yes, the current limit is adjustable via an external resistor — it can be set from below 100 mA up to the 1.1 A maximum output, which allows the designer to tailor the trip threshold to the load's inrush and steady-state current."},{"question":"What is the Rds(on) of the TPS2550DBVT?","answer":"The typical on-resistance is 85 mOhm at 25°C junction, measured at Vload = 5 V.
