Product details

Package and temperature range

Housed in an 8-SOIC package (0.154″ body width, 3.90 mm), surface-mount, with a -40°C to 85°C operating range. That industrial temperature grade covers most factory-floor and outdoor telecom enclosures. The SOIC-8 footprint is a standard one — no surprises for the pick-and-place, and easy to hand-rework if needed. No lab, no bench, let us go — a technician can swap this on site with basic tools.

Lifecycle and sourcing

The MAX819LESA+ carries an Active lifecycle status with ROHS3 compliance.

Frequently asked questions

What is the reset timeout of MAX819LESA+?

The reset timeout is a minimum of 140 ms, ensuring the downstream processor stays in reset long enough for the supply to stabilize after a brownout or power-up.

Is MAX819LESA+ compatible with 5V systems?

Yes, the 4.65 V threshold is designed for monitoring a 5 V supply rail. It asserts reset when the rail drops below 4.65 V, which is typical for 5 V logic systems.
