Built-in fault protection includes fixed current limiting, over-temperature shutdown, and undervoltage lockout (UVLO). A status flag output reports overcurrent or thermal fault conditions back to the system controller.","metaTitle":"TPS2051BQDRQ1 Automotive High-Side Power Switch, 70mOhm","metaDescription":"Texas Instruments TPS2051BQDRQ1 — AEC-Q100 qualified high-side power switch, 70 mOhm typical Rds(on), 500 mA output, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"Automotive, AEC-Q100","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-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":"-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":"$1.0900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/425b520d02a966726f977d16580a3832.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2051BQDRQ1/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS2051BQDRQ1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS2051BQDRQ1 when reusing this data.
