The reset timeout is adjustable/selectable via an external capacitor on the CT pin, letting you match the delay to the power-up settling time of the downstream load. For a typical microcontroller with a 10 ms startup, you'd pick a capacitor that sets the timeout to around 20 ms to guarantee the supply is stable before the MCU starts executing code. The active-low, open-drain output lets you wire-OR the reset signal with other supervisors or a manual reset button on the same pull-up resistor. The output can sink enough current to drive the reset input of a CMOS MCU or FPGA directly.","metaTitle":"TPS3808G30DBVRG4 Simple Reset/Power-On Reset","metaDescription":"Texas Instruments TPS3808G30DBVRG4 simple reset IC, active-low open-drain output, 2.79V threshold, adjustable timeout, -40°C 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)","Mounting Type":"Surface Mount","Reset Timeout":"Adjustable/Selectable","Package / Case":"SOT-23-6","lifecycle_stage":"eol_hot","Base Product Number":"TPS3808","Voltage - Threshold":"2.79V","Operating Temperature":"-40°C~125°C(TJ)","Supplier Device Package":"SOT-23-6","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.2200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3f65002da94aeb5b2adfcd3958ef5148.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3808G30DBVRG4/alternatives.json"},"ai":{"faq":[{"question":"How do I adjust the reset timeout on TPS3808G30DBVRG4?","answer":"The reset timeout is adjustable via an external capacitor connected to the CT pin.
