The 6-uDFN package (1.5x1 mm) is tiny — you will need a microscope to read the marking, but the footprint saves real estate on a dense board. Surface-mount only; no socket option here, so plan for reflow or hot-air rework. ## Active production, no end-of-life pressure The MAX6381LT46D3+T carries an Active lifecycle status. No last-time-buy window, no NRND flag — it is a current-production part you can specify into a new BOM without worrying about a sudden EOL notice. ROHS3 compliant, so it clears European and global assembly lines without exemption paperwork.","metaTitle":"MAX6381LT46D3+T Simple Reset/Power-On Reset, 4.63V Threshold","metaDescription":"MAX6381LT46D3+T from Analog Devices is a simple reset/power-on reset IC with 4.63V threshold, 140ms timeout, active-low push-pull output. -40°C to 125°C","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":"4.63V","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":"https://www.analog.com/media/en/technical-documentation/data-sheets/max6381-max6390.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the exact reset threshold voltage of MAX6381LT46D3+T?","answer":"The reset threshold voltage is 4.63V. This is the voltage at which the device asserts reset as the supply falls, and releases reset after the timeout once the supply rises above this level."},{"question":"Can I use MAX6381LT46D3+T as a replacement for a MAX6381 with a different threshold?","answer":"The MAX6381 family includes multiple threshold voltage options. The LT46D3 variant is fixed at 4.63V. If your design calls for a different threshold, you would need a different suffix within the MAX6381 family — they share the same pinout and package options, but the threshold is set at the factory and not adjustable."},{"question":"What is the difference between MAX6381 and MAX803?","answer":"Both are simple reset ICs, but the MAX6381 offers more threshold voltage options and a smaller package (6-uDFN vs SOT-23 for the MAX803). The MAX803 uses an open-drain output that requires an external pull-up resistor, while the MAX6381LT46D3+T uses a push-pull output that drives the reset line directly without a pull-up."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX6381LT46D3T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX6381LT46D3T when reusing this data.
