For a BOM that already uses this switch, the procurement risk is manageable in the short term, but any new design should select a current-production alternative from the TPS255x family or a pin-compatible second source. The 1.1 A maximum continuous output sets the hard ceiling for the downstream load. The adjustable current limit (set via an external resistor) allows the designer to trip at a lower threshold, protecting the load and the switch itself. The 100 mOhm typical Rds(on) means a voltage drop of roughly 110 mV at full load — enough to matter in a 3.3 V rail if the load is sensitive to supply droop. The slew-rate control feature limits the turn-on current surge, which is useful when driving capacitive loads like USB ports or peripheral power domains. ## Package and mounting — 6-WSON exposed pad The datasheet specifies a recommended copper area and via count for the thermal pad — the device's junction-to-ambient thermal resistance depends heavily on this layout. Without proper thermal management, the 1.1 A continuous current can push the junction temperature above the 150°C absolute maximum, especially in a high-ambient environment. The package is moisture-sensitive; verify the MSL level before reflow.","metaTitle":"TPS2550DRVT Power Switch, 1.1A, NRND – Sourcing & Specs","metaDescription":"Texas Instruments TPS2550DRVT high-side power switch, 1.1A max output, 2.5V–6.5V load, 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)":"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":"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":"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/TPS2550DRVT/alternatives.json"},"ai":{"faq":[{"question":"Is the TPS2550DRVT still available or obsolete?","answer":"It is not yet obsolete, but TI may issue a last-time-buy notice at any time.
