The active-low, open-drain output pulls low when the supply dips below threshold and releases after the programmed delay — a clean power-up sequence for the downstream logic. ## Open-drain output — resistor not included Without it the output never pulls high and the downstream device stays in reset. The resistor value is not critical — 10 kΩ to 100 kΩ works for most CMOS inputs — but the BOM must account for it. ## 125°C junction — industrial and automotive zones The SOT-23-6 package keeps the footprint small; the 0.95 mm pitch is hand-solderable for prototype rework.","metaTitle":"TPS3808G50DBVTG4 Simple Reset/Power-On Reset","metaDescription":"Texas Instruments TPS3808G50DBVTG4 simple reset IC with 4.65V threshold, active-low open-drain output, SOT-23-6, -40°C to 125°C.","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)","Mounting Type":"Surface Mount","Reset Timeout":"Adjustable/Selectable","Package / Case":"SOT-23-6","lifecycle_stage":"eol_hot","Base Product Number":"TPS3808","Voltage - Threshold":"4.65V","Operating Temperature":"-40°C~125°C(TJ)","Supplier Device Package":"SOT-23-6","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.0000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3f65002da94aeb5b2adfcd3958ef5148.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3808G50DBVTG4/alternatives.json"},"ai":{"faq":[{"question":"Does TPS3808G50DBVTG4 require an external pull-up resistor on the reset output?","answer":"Yes — the output is open drain, so a pull-up resistor to the monitored rail or the load's I/O voltage is required for the output to drive a valid logic-high level.
