The status flag output (open-drain, active low) asserts when current limit or thermal fault occurs, so a host GPIO can log the event or initiate a retry sequence. The switch is non-inverting and requires no Vcc supply — it's self-powered from the load voltage rail. ## Package and footprint — the exposed-pad detail The footprint is compatible with standard TSSOP-8 land patterns, but the centre pad must be connected to a copper plane — preferably the ground plane — to meet the datasheet's thermal resistance targets. Without that pad soldered, the switch derates faster above 85°C ambient.","metaTitle":"TPS2051BDGNR High-Side Power Switch, 70mOhm, 500mA, Active","metaDescription":"Texas Instruments TPS2051BDGNR high-side power switch with 70 mOhm typical Rds(on), 500 mA output, active lifecycle.","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); Cut Tape (CT)","Features":"Status Flag","Interface":"On/Off","Input Type":"Non-Inverting","Output Type":"N-Channel","Switch Type":"General Purpose","Rds On (Typ)":"70mOhm","Mounting Type":"Surface Mount","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width) Exposed Pad","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":"-40°C~125°C(TJ)","Current - Output (Max)":"500mA","Supplier Device Package":"8-HVSSOP","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.1200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fd9b875e52b121c213f56fbd3fcd8141.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2051BDGNR/alternatives.json"},"ai":{"faq":[{"question":"What is the exact Rds(on) of TPS2051BDGNR and how does it affect power dissipation?","answer":"The typical Rds(on) is 70 mOhm.
