That threshold is set for a nominal 3.3 V supply — it triggers at roughly 89% of nominal, so the reset fires before the downstream logic sees a brownout. The reset stays low for a minimum of 20 ms after the rail recovers, giving the supply time to stabilise before the processor starts. The SOT-23-6 package is a 6-pin surface-mount footprint, 2.9 mm × 1.6 mm body, so it fits on tight mixed-signal boards without eating layout space.","metaTitle":"TPS3813K33DBVT Simple Reset/Power-On Reset, 2.93V Threshold","metaDescription":"Texas Instruments TPS3813K33DBVT simple reset IC, active-low open-drain output, 2.93V threshold, 20ms min timeout, -40°C to 85°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); Cut Tape (CT)","Mounting Type":"Surface Mount","Reset Timeout":"20ms Minimum","Package / Case":"SOT-23-6","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"TPS3813","Voltage - Threshold":"2.93V","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"SOT-23-6","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.2500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/bdcb50ac2bbb4403520bc84b0d95bb38.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3813K33DBVT/alternatives.json"},"ai":{"faq":[{"question":"Is TPS3813K33DBVT compatible with 3.3 V systems?","answer":"Yes.
