Product details

Package and mounting — SC-70-5 footprint

Housed in a 5-pin SC-70-5 (also SOT-353) surface-mount package, this part fits tight PCB layouts where board space is at a premium. The supplier device package is SC-70-5, so verify the land pattern matches your assembly house's capability for fine-pitch soldering. Store the reels dry — SC-70 moisture sensitivity is moderate but worth noting for long-term shelf storage.

Temperature grade and operating environment

Rated for -40°C to 85°C ambient, the industrial temperature range covers outdoor telecom cabinets, factory-floor PLCs, and engine-bay electronics. No derating curve is needed for most environments, but keep the junction temperature below the absolute maximum if the board runs hot near the supply regulator.

Frequently asked questions

What is the reset threshold of MAX825LEXK+?

The reset threshold is 4.63V, making it suitable for monitoring 5V supply rails. The output asserts reset when VCC drops below this level and releases after the 140ms timeout once the supply recovers.

Is MAX825LEXK+ active high or low output?

The MAX825LEXK+ offers both active-high and active-low reset outputs from the same push-pull stage. Which pin you use determines the polarity — the part itself supports both options.
