The open-drain output lets you wire-OR it with other supervisors or pull it up to a different voltage domain. This part is built for low-voltage core rails — think 0.9V or 1.0V supplies powering an FPGA core, a DSP, or a modern MCU. The active-low reset signal is what most processors expect on their nRST pin. The adjustable timeout (set via an external capacitor) gives you flexibility to match the power-up settling time of the downstream device. ## Temperature range and package — board-fit details Surface-mount mounting, shipped in Tape & Reel (TR) — standard for automated pick-and-place. No exposed thermal pad to worry about; the junction-to-ambient thermal resistance is handled by the copper pad area on the PCB.","metaTitle":"TI TPS3808G09DBVTG4 Simple Reset/Power-On Reset","metaDescription":"Texas Instruments TPS3808G09DBVTG4 is a simple reset/power-on reset IC with 0.84V threshold, active-low open-drain output, and adjustable timeout.","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":"0.84V","Operating Temperature":"-40°C~125°C(TJ)","Supplier Device Package":"SOT-23-6","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.3200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3f65002da94aeb5b2adfcd3958ef5148.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3808G09DBVTG4/alternatives.json"},"ai":{"faq":[{"question":"What is the reset timeout of the TPS3808G09DBVTG4?","answer":"The reset timeout is adjustable or selectable via an external capacitor. The datasheet provides the capacitor-value-to-timeout relationship; the range covers milliseconds to several seconds depending on the capacitor chosen."},{"question":"Can the TPS3808G09DBVTG4 replace the TPS3808G09DBVR?","answer":"The TPS3808G09DBVTG4 and TPS3808G09DBVR share the same base part number (TPS3808) and the same 0.84V threshold. The suffix difference is packaging — the DBVTG4 is Tape & Reel, while the DBVR is typically in a different reel or tube configuration. Electrically they are identical; check the reel quantity and tape width for your assembly line."},{"question":"Is the TPS3808G09DBVTG4 RoHS compliant?","answer":"The part is listed with a standard TI part number suffix that typically indicates RoHS compliance and green (halogen-free) status.
