LM8365

Micropower Undervoltage Sensing Circuits with

Programmable Output Delay

General Description

Features

n Extremely Low Quiescent Current: 0.65µA, at V_IN

2.87V

The LM8365 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 Complementary or Open Drain Output

n Programmable output delay by external Capacitor

(100ms typ with 0.1µF)

n Input Voltage Range: 1V to 6V

n Surface Mount Package (5-Pin SOT23)

n Pin for pin compatible with MC33465

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

with an active low, open drain or CMOS, output. These

devices feature a very low quiescent current of 0.65µA typi-

cal. The LM8365 series features a highly accurate voltage

reference, a comparator with precise thresholds and built-in

hysterisis to prevent erratic reset operation, a time delayed

output which can be programmed by the system designer,

and guaranteed Reset operation down to 1.0V with ex-

tremely low standby current.

Applications

n Low Battery Detection

n Microprocessor Reset Controller

n Power Fail Indicator

These devices are available in the space saving 5-Pin

SOT23 surface mount package. For additional undervoltage

thresholds and output options, please contact National

Semiconductor.

n Battery Backup Detection
