Unlike adjustable-limit switches, this part does not require an external sense resistor or set resistor. Fault protection includes over-temperature shutdown and undervoltage lockout (UVLO); the open-drain Status Flag (active low) asserts when the switch is in current limit or thermal shutdown, letting a host controller detect the fault. The 8-SOIC package's thermal pad (if present on the PCB layout) helps keep the junction below the thermal-shutdown threshold under sustained 500 mA load. The Tape & Reel (TR) packaging option is suited for automated pick-and-place assembly.","metaTitle":"TPS2051BDRG4 USB Power Switch, 70 mOhm, 500 mA, 8-SOIC","metaDescription":"Texas Instruments TPS2051BDRG4 high-side power-distribution switch, 70 mOhm Rds(on), 500 mA output, -40°C to 125°C, 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)":"70mOhm","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","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-SOIC","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fd9b875e52b121c213f56fbd3fcd8141.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2051BDRG4/alternatives.json"},"ai":{"faq":[{"question":"Is TPS2051BDRG4 a direct replacement for TPS2051?","answer":"The TPS2051BDRG4 is a specific ordering code within the TPS2051 base product family. The 'BDRG4' suffix indicates the 8-SOIC package and Tape & Reel packaging. If your BOM calls for the TPS2051 in an 8-SOIC package and Tape & Reel format, this is the correct variant. Confirm the package code on your existing part marking before substituting."},{"question":"What is the current limit of TPS2051BDRG4?","answer":"The TPS2051BDRG4 has a fixed current limit that clamps the output at 500 mA maximum. There is no external resistor to set the limit — the protection circuit is internal and non-adjustable.
