This is useful when the downstream MCU or FPGA needs a specific hold-off time to stabilise its internal regulators or oscillators before the reset de-asserts. The same BOM line can cover a 1.25 ms delay for a fast-starting Cortex-M0 or a 200 ms delay for a larger SoC with a PLL lock time — just change the capacitor, not the supervisor part number. ## SOT-23-6 footprint and open-drain output Housed in a 6-pin SOT-23 package, this supervisor takes up minimal board area — about 3 mm × 3 mm. The open-drain output lets you wire-OR the reset signal with other supervisors or a manual reset button, pulling the line low from any source. The output requires a pull-up resistor to the logic supply rail (typically 10 kΩ to 100 kΩ). Because the output is open drain, it can be pulled up to a different voltage than the monitored rail, which is handy when the supervisor monitors a 3.3V rail but the processor's reset input runs at 1.8V.","metaTitle":"TPS3808G33MDBVREP Simple Reset/Power-On Reset","metaDescription":"Texas Instruments TPS3808G33MDBVREP simple reset/power-on reset IC with 3.07V threshold, active-low open-drain output, adjustable timeout, -55°C to 125°C range.","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":"-55°C~125°C(TJ)","Supplier Device Package":"SOT-23-6","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.6700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/162c3f0e990a4140757581a0571f2b02.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3808G33MDBVREP/alternatives.json"},"ai":{"faq":[{"question":"Does TPS3808G33MDBVREP work with 3.3V logic?","answer":"Yes. The 3.07V threshold is designed to supervise a 3.3V supply rail. The open-drain output can be pulled up to any voltage within the absolute maximum rating of the output transistor, including 3.3V logic levels. The reset is active low, so it pulls the line low when the monitored rail falls below the threshold."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS3808G33MDBVREP","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS3808G33MDBVREP when reusing this data.
