The active-low, open-drain output pulls low when VDD drops below threshold and stays asserted through the reset timeout period after the supply recovers. ## Adjustable reset timeout — sequencing without a second timer The reset timeout is adjustable/selectable via an external capacitor on the CT pin — no fixed-delay variant locks you into a single power-up profile. This matters when the downstream MCU or FPGA needs a specific hold time after the rail stabilises before releasing reset.","metaTitle":"TPS3808G33DBVT Simple Reset/Power-On Reset, 3.07V Threshold","metaDescription":"Texas Instruments TPS3808G33DBVT — Simple Reset/Power-On Reset, active-low open-drain output, 3.07V threshold, adjustable timeout, -40 to 125°C, SOT-23-6.","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":"3.07V","Operating Temperature":"-40°C~125°C(TJ)","Supplier Device Package":"SOT-23-6","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.0300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3f65002da94aeb5b2adfcd3958ef5148.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3808G33DBVT/alternatives.json"},"ai":{"faq":[{"question":"How do I configure the reset timeout on TPS3808G33DBVT?","answer":"The reset timeout is adjustable/selectable by connecting an external capacitor between the CT pin and ground.
