That threshold sits at roughly 70% of a 3.3V rail — it trips before the downstream logic loses state, but stays above the brownout floor of most 3.3V-powered MCUs and FPGAs. ## Active-low open-drain output with adjustable timeout Reset output is active-low, open-drain — it pulls low when VDD drops below 2.33V and releases after the reset timeout expires once the rail recovers. The timeout is adjustable via an external capacitor on the CT pin, which lets you tune the delay to match the power-up settling time of the downstream device. ## 125°C junction rating — hot environments covered The SOT-23-6 package keeps the footprint small, but the junction-to-ambient thermal path relies on PCB copper area — a solid ground pour under the package helps keep die temperature within the rated envelope. ## Active lifecycle — no last-time-buy watch needed That means it is a current-production part eligible for new-design qualification and standard-channel replenishment — no LTB math, no broker scramble for date codes.","metaTitle":"TPS3808G25DBVT TI Simple Reset/Power-On Reset","metaDescription":"Texas Instruments TPS3808G25DBVT voltage supervisor: active-low open-drain reset, 2.33V threshold, adjustable timeout, 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); 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":"2.33V","Operating Temperature":"-40°C~125°C(TJ)","Supplier Device Package":"SOT-23-6","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.7000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3f65002da94aeb5b2adfcd3958ef5148.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3808G25DBVT/alternatives.json"},"ai":{"faq":[{"question":"Is TPS3808G25DBVT a drop-in replacement for TPS3808G25?","answer":"The TPS3808G25DBVT is the standard SOT-23-6 variant of the TPS3808G25 voltage supervisor. The base part number TPS3808G25 refers to the same die with the same 2.33V threshold — the DBVT suffix specifies the SOT-23-6 package and tape-and-reel delivery. Any TPS3808G25 in the same package is footprint-identical; check the package code on your BOM line before swapping."},{"question":"How do I set the reset timeout on TPS3808G25DBVT?","answer":"The reset timeout is adjustable by connecting a capacitor between the CT pin and ground. The timeout period scales linearly with capacitance — a specific value table is in the datasheet. The part also offers a fixed internal timeout option if the CT pin is left floating, but the adjustable mode gives you control over the power-up sequencing delay."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS3808G25DBVT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS3808G25DBVT when reusing this data.
