The 2.25 V threshold is the trip point: when the monitored voltage drops below this level, the reset output asserts. For a 2.5 V logic rail, this gives about 250 mV of margin before the supervisor triggers — enough headroom to catch a sagging supply without nuisance resets on ripple. The 120 ms minimum reset timeout is a fixed delay, not adjustable. It is long enough for most crystal oscillators and PLLs to lock, but if your processor needs a longer hold time, you would need a different supervisor with a programmable or longer timeout period. Housed in a SOT-23-3 package, this is a three-pin device — supply, ground, and reset output.","metaTitle":"TPS3809J25DBVTG4 Simple Reset/Power-On Reset","metaDescription":"Texas Instruments TPS3809J25DBVTG4 simple reset supervisor, active-low push-pull output, 2.25V threshold, 120ms timeout, -40°C to 85°C, SOT-23-3.","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":"Push-Pull, Totem Pole","Series":"-","Package":"Tape & Reel (TR)","Mounting Type":"Surface Mount","Reset Timeout":"120ms Minimum","Package / Case":"TO-236-3, SC-59, SOT-23-3","lifecycle_stage":"eol_hot","Base Product Number":"TPS3809","Voltage - Threshold":"2.25V","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"SOT-23-3","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.8600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f26b91921dc9877edaf2023da706c342.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3809J25DBVTG4/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS3809J25DBVTG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS3809J25DBVTG4 when reusing this data.
