The open-drain active-low output lets the reset signal pull down to whatever logic rail the downstream MCU or FPGA uses, provided an external pull-up resistor is fitted. ## Automotive-grade qualification and temperature envelope For a production BOM in an automotive ECU, the Q1 suffix in the order code is the flag that confirms the grade; the base TPS3808 family also has non-automotive variants, so the full order code matters when ordering. ## Adjustable reset timeout — one capacitor sets the delay The reset timeout period is adjustable via a single capacitor connected to the CT pin. The designer picks the hold-off time — typically a few milliseconds to several hundred milliseconds — that guarantees the downstream processor's supply and oscillator have settled before the reset is released. No programming interface or register write is needed; it is a purely analog delay that stays set across power cycles. A fixed-time variant exists in the TPS3808 family, but the 'G50' with adjustable timeout gives the BOM flexibility to tune the delay without a PCB spin. ## SOT-23-6 footprint — what the layout needs The supplier device package is SOT-23-6, a 6-pin surface-mount package. The open-drain output needs a pull-up resistor to the reset rail. ## Active production — no LTB shadow on the BOM For a production line that already qualifies this supervisor, the risk of a forced respin due to obsolescence is low. The base product number TPS3808 covers a range of voltage threshold options and fixed/adjustable timeout variants, so if a future design moves to a different rail voltage, the footprint-compatible sibling can be specified without a board layout change.","metaTitle":"TPS3808G50QDBVRQ1 Simple Reset/Power-On Reset","metaDescription":"Texas Instruments TPS3808G50QDBVRQ1 is a Simple Reset/Power-On Reset IC with a 4.65V threshold, open-drain active-low output, adjustable timeout, AEC-Q100","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":"Automotive, AEC-Q100","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":"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/af47015ed1397389fa8a7e17d86bf4af.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3808G50QDBVRQ1/alternatives.json"},"ai":{"faq":[{"question":"Is the TPS3808G50QDBVRQ1 AEC-Q100 qualified for automotive use?","answer":"Yes, it is AEC-Q100 qualified, as indicated by the Q1 suffix and the Series field listing Automotive, AEC-Q100."},{"question":"How do I program the reset timeout on the TPS3808G50QDBVRQ1?","answer":"The reset timeout is adjustable by connecting a capacitor between the CT pin and ground.
