The reset output is active-low, open-drain, so it can be wire-ORed with other reset sources or pulled up to a different voltage than the monitored rail. ## 20 ms reset timeout — timing for the downstream boot sequence The minimum reset timeout of 20 ms holds the reset line low long enough for the downstream processor or FPGA to complete its power-on reset sequence. If the timeout were shorter, the processor might start before its internal regulators and oscillators have settled; if longer, the system would waste time waiting. The 20 ms figure is a datasheet minimum, so the actual timeout will be longer — design the system timing budget assuming the minimum, not a typical value. ## SOT-23-6 footprint and industrial temperature range The SOT-23-6 package is a compact surface-mount footprint, 6 pins, with a 0.95 mm pitch typical for this family. For designs that need -40°C to 125°C, look at the TPS382x family; for the same threshold in a smaller package, the TPS3808 series offers a 1.6 mm x 1.6 mm X2SON option. For a simple reset IC, this is the expected lifecycle — these parts tend to stay active for years because they are commodity building blocks. No official successor or second-source cross-reference is listed, but the TPS3813 family has been stable in the TI portfolio for over a decade.","metaTitle":"TPS3813K33DBVR Simple Reset/Power-On Reset IC","metaDescription":"TI TPS3813K33DBVR simple reset/power-on reset IC with active-low open-drain output, 2.93V threshold, 20ms min reset timeout, SOT-23-6, -40°C to 85°C.","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":"$1.8700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/bdcb50ac2bbb4403520bc84b0d95bb38.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3813K33DBVR/alternatives.json"},"ai":{"faq":[{"question":"Does TPS3813K33DBVR have an active-low reset?","answer":"Yes, the reset output is active-low with an open-drain or open-collector output stage.
