GENERAL DESCRIPTION  
The ADM6315 is a reliable voltage-monitoring device that is  
suitable for use in most voltage-monitoring applications.  
The manual reset function is very useful, especially if the circuit  
in which the ADM6315 is operating enters into a state that can  
be detected only by the user. Allowing the user to reset a system  
manually can reduce the damage or danger that could otherwise  
be caused by an out-of-control or locked-up system.  
The ADM6315 is designed to monitor as little as a 1.8%  
degradation of a power supply voltage. The ADM6315 can  
monitor all voltages (at 100 mV increments) from 2.5 V to 5 V.  
The ADM6315 is available in a cost- and space-efficient  
SOT-143 package.  
Included in this circuit is a debounced manual reset input.  
RESET  
MR  
can be activated using an ordinary switch (pulling  
low), a low input from another digital device, or a degradation  
of the supply voltage.
