It is a Simple Reset/Power-On Reset type — no adjustable delay, no watchdog, just a clean power-good flag for the processor or FPGA. The active-low, open-drain output lets you wire-OR multiple reset sources or pull up to a different logic level, handy in mixed-voltage designs. Reset timeout is a minimum of 100ms, long enough to let the main supply and oscillator stabilize before the CPU starts executing. The SOT-23-3 package fits tight layouts, and the -40°C to 85°C range covers industrial control, telecom, and outdoor equipment. ## Open-drain output — wired-OR and level translation The open-drain output allows the reset line to be shared with other open-drain devices. The pull-up resistor can connect to a different supply than VCC. ## Active lifecycle — no LTB pressure The MAX6348UR40+T carries an Active lifecycle status. No last-time-buy clock is ticking, so it is safe to qualify into a new BOM or replenish an existing line without worrying about an imminent EOL notice. ROHS3 compliance is confirmed, so it meets the latest EU restriction requirements.","metaTitle":"MAX6348UR40+T Simple Reset/Power-On Reset, 4V Threshold","metaDescription":"MAX6348UR40+T from Analog Devices is a simple reset/power-on reset IC with 4.00V threshold, active-low open-drain output, 100ms min reset timeout.","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":"Open Drain or Open Collector","Package":"Cut Tape (CT)","Mounting Type":"Surface Mount","Reset Timeout":"100ms Minimum","Package / Case":"TO-236-3, SC-59, SOT-23-3","lifecycle_stage":"eol_hot","Voltage - Threshold":"4V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"SOT-23-3","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.1","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.10000","currency":"USD"},{"qty":10,"price":"$3.68300","currency":"USD"},{"qty":25,"price":"$3.48200","currency":"USD"},{"qty":100,"price":"$3.01780","currency":"USD"},{"qty":250,"price":"$2.86304","currency":"USD"},{"qty":500,"price":"$2.56902","currency":"USD"},{"qty":1000,"price":"$2.16664","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/max6326-max6348.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the reset timeout of MAX6348UR40+T?","answer":"The reset timeout is a minimum of 100ms. This ensures the processor has a stable power-up sequence before the reset is released."},{"question":"What is the output configuration of MAX6348UR40+T?","answer":"The output is active-low, open drain or open collector.

The MAX6348UR40+T monitors at 4.00V; the MAX6347 would have a different threshold. Check the threshold voltage of your original part before substituting — they are not drop-in replacements unless the thresholds match."},{"question":"Is MAX6348UR40+T RoHS compliant?","answer":"Yes, it is ROHS3 Compliant, meeting the latest EU RoHS requirements."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX6348UR40T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX6348UR40T when reusing this data.
