Both active-high and active-low reset outputs are provided, and the output stage is push-pull (totem pole), so no external pull-up resistor is needed — that saves a resistor per output on the BOM. The minimum reset timeout of 140 ms gives the downstream processor or FPGA enough time to stabilize its internal state before the reset de-asserts. This is a fixed delay, not adjustable, so confirm it meets your system's power-on reset requirement. ## Package and thermal design note The package footprint matches standard 8-TSSOP land patterns, but the center pad adds a thermal via requirement. Surface-mount assembly; the tube delivery is fine for prototyping but production volumes typically shift to tape-and-reel — confirm the reel option with your distributor when ordering. ## Temperature grade and operating range Not qualified to AEC-Q100, so it is not the choice for under-hood automotive or powertrain applications. The base product number TPS3307 covers multiple threshold variants — confirm the -33DGN suffix matches your BOM before ordering.","metaTitle":"TPS3307-33DGN Multi-Voltage Supervisor","metaDescription":"TI TPS3307-33DGN multi-voltage supervisor monitors three rails with 2.93V, 4.55V, and adjustable thresholds.","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 High/Active Low","Output":"Push-Pull, Totem Pole","Series":"-","Package":"Tube","Mounting Type":"Surface Mount","Reset Timeout":"140ms Minimum","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width) Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"TPS3307","Voltage - Threshold":"2.93V, 4.55V, Adj","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"8-HVSSOP","Number of Voltages Monitored":"3"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.0100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8827b21deee1fba8c815128819be5cd7.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3307-33DGN/alternatives.json"},"ai":{"faq":[{"question":"What is the reset timeout for TPS3307-33DGN?","answer":"The reset timeout is a minimum of 140 ms — a fixed delay that ensures a stable reset pulse for processor or FPGA initialization after all monitored rails are valid."},{"question":"What voltages does TPS3307-33DGN monitor?","answer":"It monitors three voltages: fixed thresholds at 2.93 V and 4.55 V, plus one adjustable channel that can be set via an external resistor divider for non-standard rail voltages."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS3307-33DGN","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS3307-33DGN when reusing this data.
