It prevents the processor from starting until the supply has been stable for over a tenth of a second, which covers most power-supply ramp-up transients and oscillator start-up delays. If your system needs a shorter or longer delay, this part is fixed — no external capacitor adjustment. Push-pull output means the reset pin drives high and low actively. No external pull-up resistor is needed, saving one component per supervisor channel. The output is active-low, so it connects directly to the /RESET pin of most MCUs and FPGAs. ## Lifecycle and compliance note The MAX6712REXS carries an active lifecycle status. One important flag: this part is RoHS non-compliant. If your BOM requires RoHS conformance for EU markets or a corporate environmental policy, you will need either an exemption waiver or a lead-free alternative. Verify your assembly house's acceptance of non-RoHS material before committing the line.","metaTitle":"MAX6712REXS Simple Reset/Power-On Reset, 2.63V Threshold","metaDescription":"MAX6712REXS is an active simple reset supervisor with 140ms timeout, push-pull output, -40°C to 125°C range.

The MAX6712REXS uses a 2.63V threshold; other variants in the same SC-70-4 footprint offer thresholds for 1.8V, 2.5V, 3.0V, 3.3V, and 5.0V rails. If your rail voltage changes, select the variant with the matching threshold — the pinout and reset timeout remain identical."},{"question":"What does the 2.63V threshold mean for my 3.3V design?","answer":"On a 3.3V rail, the 2.63V threshold trips at roughly 80% of nominal voltage. This provides a healthy margin against brown-out conditions while avoiding false resets from normal supply ripple. For a 2.5V rail, the margin is tighter — verify that your processor's minimum operating voltage is below 2.63V to prevent unintended resets."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX6712REXS","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX6712REXS when reusing this data.
