The status flag output (open-drain, active low) asserts when the switch is in current limit or thermal shutdown, so a downstream GPIO or PLC input can log the fault without an ADC. The enable input is non-inverting — logic high turns the switch on.","metaTitle":"Texas Instruments TPS2051ADR USB Power Switch, 80 mOhm","metaDescription":"Texas Instruments TPS2051ADR high-side power switch, 80 mOhm Rds(on), 500 mA output, active lifecycle, 8-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR)","Features":"Status Flag","Interface":"On/Off","Input Type":"Non-Inverting","Output Type":"N-Channel","Switch Type":"General Purpose","Rds On (Typ)":"80mOhm","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Active","Voltage - Load":"2.7V ~ 5.5V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Fixed), Over Temperature, UVLO","Number of Outputs":"1","Base Product Number":"TPS2051","Output Configuration":"High Side","Ratio - Input:Output":"1:1","Operating Temperature":"0°C~125°C(TJ)","Current - Output (Max)":"500mA","Supplier Device Package":"8-SOIC","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.1160","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a3c922d863bc9807df1696a6e8de927a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2051ADR/alternatives.json"},"ai":{"faq":[{"question":"What is the TPS2051ADR used for?","answer":"It is a single-channel high-side power distribution switch, typically used for USB port power, general-purpose 5 V or 3.3 V rail switching, and fault-protected power distribution in industrial control and telecom equipment."},{"question":"Is the TPS2051ADR RoHS compliant?","answer":"The part ships in a Tape & Reel package and is listed with a standard 8-SOIC body.
