The 5µs propagation delay means the reset pin pulls low fast enough to hold the processor in reset before a brownout corrupts the program counter. Housed in a SOT-23-6 package with 0.95 mm pitch, the part reflows cleanly on a standard FR-4 board. ## Industrial temperature grade for the shop floor The SOT-23-6 package's low thermal mass means it tracks the ambient quickly — no warm-up delay before the reset thresholds are valid.","metaTitle":"TPS3806J20DBVR Multi-Voltage Supervisor, Active Low Reset","metaDescription":"Texas Instruments TPS3806J20DBVR multi-voltage supervisor monitors 1.8V and adjustable rail.","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":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Reset Timeout":"5µs Typical Propagation Delay","Package / Case":"SOT-23-6","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"TPS3806","Voltage - Threshold":"1.8V, Adj","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"SOT-23-6","Number of Voltages Monitored":"2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6540","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f5dc6a26a484059ca303b8166bb23b17.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3806J20DBVR/alternatives.json"},"ai":{"faq":[{"question":"What is the reset timeout of the TPS3806J20DBVR?","answer":"The TPS3806J20DBVR has a typical propagation delay of 5µs from the supply crossing the threshold to the reset output asserting.
