GENERAL DESCRIPTION  
The ADM6384 is a supervisory circuit that monitors power  
supply voltage levels in microprocessor-based systems. A  
power-on reset signal is generated when the supply voltage  
rises to a preset threshold level. The debounced manual reset  
input of the ADM6384 can be used to initiate a reset by means  
of an external push-button or logic signal.  
The part is available in a choice of 31 reset threshold options,  
from 1.58 V to 5.0 V. The minimum reset timeout periods are  
1 ms, 20 ms, 140 ms, and 1120 ms.  
The ADM6384 is available in a 4-lead SC70 package and typi-  
cally consumes only 7 μA, making it suitable for use in low  
power, portable applications.
