4.35V threshold supervisor for 5V rails
The Maxim DS1811R-10+T&R is a single-channel voltage supervisor from the EconoReset family, designed to monitor a 5V supply rail and assert a reset signal when the voltage drops below 4.35V.

Product details
Frequently asked questions
What is the exact reset threshold voltage of DS1811R-10+T&R?
The reset threshold voltage is 4.35V. When the monitored supply falls below this level, the active-low open-drain output asserts reset.
Is DS1811R-10+T&R compatible with 5V systems?
Yes, the 4.35V threshold is specifically intended for monitoring a nominal 5V supply rail. The part asserts reset before the rail drops below the minimum operating voltage of most 5V logic.
Does DS1811R-10+T&R have an active low or active high reset?
The reset output is active low. The open-drain output pulls low when the monitored voltage falls below the threshold, and releases after the 100ms timeout once the supply recovers.
