LM8364

Micropower Undervoltage Sensing Circuits

General Description

Features

n Extremely Low Quiescent Current: 0.65µA, at V_IN

2.87V

The LM8364 series are micropower undervoltage sensing

circuits that are ideal for use in battery powered micropro-

cessor based systems, where extended battery life is a key

requirement.

n High Accuracy Threshold Voltage ( 2.5%)

n Open Drain Output

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 com-

parator with precise thresholds and built-in hysterisis to pre-

vent erratic reset operation, and guaranteed Reset operation

down to 1.0V with extremely low standby current.

n Input Voltage Range: 1V to 6V

n Surface Mount Package (5-Pin SOT23)

n Pin for pin compatible with MC33464

Applications

n Low Battery Detection

n Microprocessor reset Controller

n Power Fail Indicator

These devices are available in the space saving SOT23

5-pin surface mount package. For other undervoltage

thresholds and output options, please contact National

Semiconductor.

n Battery Backup Detection
