The reset output is active-low, open-drain, so it can be wire-ORed with other reset sources on the board. ## 10 ms timeout — why it matters for processor boot A shorter timeout risks the CPU starting before the oscillator or PLL has locked; a longer one delays system readiness. The 10 ms floor is a common middle ground for MCUs and simple SoCs. The SOT-23-5 package is a compact 5-pin footprint that fits on tight mixed-signal boards.","metaTitle":"TPS3838J25DBVRG4 Simple Reset/Power-On Reset","metaDescription":"Texas Instruments TPS3838J25DBVRG4 simple reset IC, active-low open-drain output, 2.25V threshold, 10ms timeout, -40°C to 85°C, SOT-23-5.","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":"10ms Minimum","Package / Case":"SC-74A, SOT-753","lifecycle_stage":"eol_hot","Base Product Number":"TPS3838","Voltage - Threshold":"2.25V","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"SOT-23-5","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/020841d6578f782f4748e70ad552a6db.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3838J25DBVRG4/alternatives.json"},"ai":{"faq":[{"question":"What is the reset timeout of TPS3838J25DBVRG4?","answer":"The reset timeout is a minimum of 10 ms.
