The 70ms minimum reset timeout keeps the downstream processor in reset long enough for both rails to settle after a power-up or brown-out event. ## Voltage thresholds and reset timing The two monitored thresholds — 1.85V and 2.92V — are fixed, not adjustable, so the TPS3306-20DGKG4 suits designs where those exact trip points align with the nominal rail voltages. The reset output is open-drain, active-low, which lets it pull down the reset line of multiple devices on the same bus without contention. The TPS3306-20DGKG4 is listed as obsolete. For BOM lines that still call out this exact MPN, the only supply path is through independent distribution — surplus inventory, new-old-stock, or broker-sourced material.","metaTitle":"TPS3306-20DGKG4 Multi-Voltage Supervisor, 1.85V/2.92V","metaDescription":"Texas Instruments TPS3306-20DGKG4 dual-voltage supervisor with 1.85V and 2.92V thresholds, 70ms reset timeout, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Type":"Multi-Voltage Supervisor","Reset":"Active Low","Output":"Open Drain or Open Collector","Series":"-","Package":"Tube","Mounting Type":"Surface Mount","Reset Timeout":"70ms Minimum","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"TPS3306","Voltage - Threshold":"1.85V, 2.92V","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"8-VSSOP","Number of Voltages Monitored":"2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3306-20DGKG4/alternatives.json"},"ai":{"faq":[{"question":"What is the reset timeout of TPS3306-20DGKG4?","answer":"The reset timeout is 70ms minimum.
