This flexibility means the same base part number covers different BOM configurations without a custom OTP variant. The SOT-23-6 package keeps the footprint small — six pins in a 2.9 mm × 1.6 mm body — which fits tight layouts on multilayer automotive PCBs where every square millimeter counts. The base product number is TPS3780, which covers the full family of adjustable-threshold supervisors. The QDBVRQ1 suffix denotes the SOT-23-6 package and the automotive (Q1) grade.","metaTitle":"TPS3780AQDBVRQ1 Multi-Voltage Supervisor, AEC-Q100, SOT-23-6","metaDescription":"Texas Instruments TPS3780AQDBVRQ1 automotive multi-voltage supervisor, monitors two adjustable thresholds, active-low open-drain reset, -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","Type":"Multi-Voltage Supervisor","Reset":"Active Low","Output":"Open Drain or Open Collector","Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Reset Timeout":"-","Package / Case":"SOT-23-6","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"TPS3780","Voltage - Threshold":"Adjustable/Selectable","Operating Temperature":"-40°C~125°C(TJ)","Supplier Device Package":"SOT-23-6","Number of Voltages Monitored":"2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.0005","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cd69844ada1a022e157d01fbc398ea37.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3780AQDBVRQ1/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between TPS3780AQDBVRQ1 and the base TPS3780?","answer":"The base TPS3780 without the Q1 suffix is the commercial/industrial grade. Functionally they are the same dual-voltage supervisor with adjustable thresholds and open-drain output, but the Q1 version is the one to specify for automotive or high-reliability industrial designs."},{"question":"What is the TPS3780AQDBVRQ1's reset output type?","answer":"The reset output is active-low, open-drain. This means it pulls low when a monitored voltage drops below threshold, and requires an external pull-up resistor to the reset rail. The open-drain configuration allows wired-OR connections with other supervisors or reset sources."},{"question":"How many voltages does the TPS3780AQDBVRQ1 monitor?","answer":"It monitors two independent voltages. Each channel has its own adjustable threshold set by external resistor dividers, so you can supervise two different supply rails — for example, a 3.3 V core rail and a 5 V I/O rail — with a single supervisor IC."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS3780AQDBVRQ1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS3780AQDBVRQ1 when reusing this data.
