LM8364  
Micropower Undervoltage Sensing Circuits  
General Description  
Features  
n Extremely Low Quiescent Current: 0.65µA, at VIN  
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.
