GENERAL DESCRIPTION
MR
RESET
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 monitored
by the ADM6315 are all voltages (at 100 mV increments) from
2.5 V to 5 V.
Included in this circuit is a debounced manual reset input.
RESET
can be activated using an ordinary switch (pulling
MR
low), a low
input from another digital device, or a degradation of the supply
voltage. 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 manually
reset a system can reduce the damage or danger that could other-
wise be caused by an out-of-control or locked-up system.
The ADM6315 comes in a cost and space efficient SOT-143
package.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although the
ADM6315 features proprietary ESD protection circuitry, permanent damage may occur on devices
subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended
to avoid performance degradation or loss of functionality.
