The open-drain, active-low output lets the reset signal wire-OR with other supervisors or a manual reset button, pulling the line low when the monitored voltage is out of tolerance. ## Adjustable timeout for sequenced power-up The reset timeout is adjustable or selectable via an external capacitor on the CT pin — no fixed timer to work around. This lets you match the reset hold time to the power-up settling of downstream FPGAs, ADCs, or MCUs that need a stable rail before de-asserting reset. The SOT-23-6 package keeps the footprint small — useful when the supervisor sits close to the monitored rail on a dense board.","metaTitle":"TPS3808G19DBVT Simple Reset/Power-On Reset IC","metaDescription":"Texas Instruments TPS3808G19DBVT is a simple reset/power-on reset IC with active-low open-drain output, 1.77V threshold, adjustable timeout, SOT-23-6 package","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Type":"Simple Reset/Power-On Reset","Reset":"Active Low","Output":"Open Drain or Open Collector","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Reset Timeout":"Adjustable/Selectable","Package / Case":"SOT-23-6","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"TPS3808","Voltage - Threshold":"1.77V","Operating Temperature":"-40°C~125°C(TJ)","Supplier Device Package":"SOT-23-6","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.5900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3f65002da94aeb5b2adfcd3958ef5148.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3808G19DBVT/alternatives.json"},"ai":{"faq":[{"question":"Does TPS3808G19DBVT have an adjustable reset timeout?","answer":"Yes.
