GENERAL DESCRIPTION  
The ADM6315 is a reliable voltage monitoring device that is  
suitable for use in most voltage monitoring applications.

The ADM6315 is designed to monitor as little as a 1.8% degra-  
dation of a power supply voltage. Voltages that can be moni-  
tored by the ADM6315 are all voltages (at 100 mV increments)  
from 2.5 V to 5 V.

Figure 1. Typical Operating Circuit  
Included in this circuit is a debounced Manual Reset input.  
Reset can be activated using an ordinary switch (pulling MR  
low), by a low input from another digital device or by a degra-  
dation of the supply voltage. The manual reset function is very  
useful, especially if the circuit in which the ADM6315 is oper-  
ating, enters into a state that can only be detected by the user.  
Allowing the user to manually reset a system can reduce the  
damage or danger that could be otherwise caused by an out of  
control or locked-up system.  
The ADM6315 comes in a cost and space efficient SOT-143  
package.
