The open-drain output lets multiple reset sources (another supervisor, a watchdog, a manual reset button) share a common pull-up resistor to the same rail — useful in multi-voltage designs where the reset signal must be valid before the core supply is up. The 8-SOIC footprint is a standard 0.154-inch body width, 3.90 mm — a common package that routes easily on two-layer boards and mates with existing layout footprints for similar supervisors.","metaTitle":"TPS3306-20QDRQ1 Multi-Voltage Supervisor, AEC-Q100, 8-SOIC","metaDescription":"Texas Instruments TPS3306-20QDRQ1 multi-voltage supervisor, AEC-Q100 qualified, monitors 1.85V and 2.92V rails, active-low open-drain reset, 70ms timeout","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":"Bulk","Mounting Type":"Surface Mount","Reset Timeout":"70ms Minimum","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"TPS3306","Voltage - Threshold":"1.85V, 2.92V","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"8-SOIC","Number of Voltages Monitored":"2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.7500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a74b05c34b77828b8e498a4909f77147.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3306-20QDRQ1/alternatives.json"},"ai":{"faq":[{"question":"What does the 'Q' in TPS3306-20QDRQ1 indicate?","answer":"The 'Q' in the order code indicates AEC-Q100 automotive qualification — the part is qualified for automotive-grade applications."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS3306-20QDRQ1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS3306-20QDRQ1 when reusing this data.
