That saves a component and a PCB trace in tight layouts. ## Active production — no end-of-life concern Because it is active, sourcing is straightforward through authorized distribution channels. The 6-uDFN package (1.5x1mm) is a space-saving surface-mount footprint — the 0.5mm pitch and small body mean it fits on dense mixed-signal boards where a larger SOT-23 supervisor would not route. The 140ms minimum reset timeout is long enough to cover most power-supply ramp-up and brown-out recovery sequences. If your rail takes longer to settle, you may need an external capacitor to extend the timeout — but for typical 3.3V or 5V rails derived from a buck converter, this part works as-is.","metaTitle":"MAX6381LT44D3+T Simple Reset/Power-On Reset, 4.38V Threshold","metaDescription":"MAX6381LT44D3+T Simple Reset/Power-On Reset IC, active-low push-pull output, 4.38V threshold, 140ms timeout, -40 to +125°C, 6-uDFN package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Simple Reset/Power-On Reset","Reset":"Active Low","Output":"Push-Pull, Totem Pole","Package":"Strip","Mounting Type":"Surface Mount","Reset Timeout":"140ms Minimum","Package / Case":"6-WFDFN","lifecycle_stage":"eol_hot","Voltage - Threshold":"4.38V","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"6-uDFN (1.5x1)","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.49","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.49000","currency":"USD"},{"qty":10,"price":"$3.77100","currency":"USD"},{"qty":25,"price":"$3.53160","currency":"USD"},{"qty":100,"price":"$3.16100","currency":"USD"},{"qty":250,"price":"$2.94300","currency":"USD"},{"qty":500,"price":"$2.79040","currency":"USD"},{"qty":1000,"price":"$2.65960","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the MAX6381LT44D3+T's reset threshold and timeout?","answer":"The output is active-low push-pull."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX6381LT44D3~3T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX6381LT44D3~3T when reusing this data.
