The SOT-23-6 package keeps the footprint small — useful when board space is tight and you need a supervisor near the processor without routing a long reset trace. ## Lifecycle and sourcing reality The MAX6343LUT is listed as Active in production. RoHS non-compliant, so verify your assembly house's exemption policy if you need lead-free.","metaTitle":"MAX6343LUT Simple Reset/Power-On Reset, 4.63V Threshold","metaDescription":"MAX6343LUT is an active-low, open-drain supervisor IC with 4.63V reset threshold, 100ms timeout, and -40°C to 125°C range.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Simple Reset/Power-On Reset","Reset":"Active Low","Output":"Open Drain or Open Collector","Package":"Bulk","Mounting Type":"Surface Mount","Reset Timeout":"100ms Minimum","Package / Case":"SOT-23-6","lifecycle_stage":"eol_hot","Voltage - Threshold":"4.63V","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"SOT-23-6","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.74","priceTiers":[{"qty":110,"price":"$2.74000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a79619920f9c91ed4ce231b800b061c3.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MAX6343LUT/alternatives.json"},"ai":{"faq":[{"question":"Is MAX6343LUT active low or active high?","answer":"Active low. The reset output goes low when the supply is out of tolerance. Because it's open drain, you need an external pull-up resistor to the logic supply to get a valid high level when reset is not asserted."},{"question":"What is the closest pin-compatible alternative to MAX6343LUT?","answer":"Within the same family, parts with different threshold voltages (e.g., 2.63V, 3.08V, 4.38V) share the same SOT-23-6 pinout and open-drain active-low output. If you need a different trip point, look at the MAX6342/MAX6344 variants — same footprint, same timeout, same temperature range."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX6343LUT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX6343LUT when reusing this data.
