LM8365 Micropower Undervoltage Sensing Circuits with Programmable Output Delay

Check for Samples: LM8365

FEATURES

DESCRIPTION

The LM8365 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.

•

Extremely Low Quiescent Current: 0.65μA, at

V_IN= 2.87V

•

High Accuracy Threshold Voltage (±2.5%)

Complementary or Open Drain Output

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 typical. The LM8365 series features

a highly accurate voltage reference, a comparator

with precise thresholds and built-in hystersis to

prevent erratic reset operation, a time delayed output

which can be programmed by the system designer,

and specified Reset operation down to 1.0V with

extremely low standby current.

Programmable output delay by external

Capacitor (100ms typ with 0.1μF)

•

Input Voltage Range: 1V to 6V

Surface Mount Package (5-Pin SOT-23)

Pin for pin compatible with MC33465

APPLICATIONS

•

Low Battery Detection

These devices are available in the space saving 5-

Pin SOT-23 surface mount package. For additional

undervoltage thresholds and output options, please

contact Texas Instruments.
