DESCRIPTION

The LM8364 series are micropower undervoltage

sensing circuits that are ideal for use in battery

powered microprocessor based systems, where

extended battery life is a key requirement.

A range of threshold voltages from 2.0V to 4.5V are

available with an active low open drain output. These

devices feature a very low quiescent current of

0.65μA typical. The LM8364 series features a highly

accurate voltage reference, a comparator with precise

thresholds and built-in hysterisis to prevent erratic reset operation, and ensured Reset operation down

to 1.0V with extremely low standby current.

These devices are available in the space saving

SOT-23 5-pin surface mount package. For other

undervoltage thresholds and output options, please
