Product details

What the MAX6712REXS does and where it fits

Housed in a 4-pin SC-70-4 (SOT-343) surface-mount package, it operates across the full -40°C to 125°C temperature range.

Key ratings and what they mean for the BOM

The 140ms minimum reset timeout is a deliberate hold-off period. 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.

Frequently asked questions

What is the closest pin-compatible alternative to MAX6712REXS?

Within the MAX6712 family, the threshold voltage is the primary differentiator. 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.

What does the 2.63V threshold mean for my 3.3V design?

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.
