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%
degradation of a power supply voltage. The ADM6315 can
monitor 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 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 available in a cost- and space-efficient
SOT-143 package.

... THEORY OF OPERATION INTERFACING TO OUTPUT OF OTHER DEVICES The ADM6315 series is designed to integrate with as many devices as possible. One feature of the ADM6315 is the RESET open- drain output, which can sink current from sources with a voltage greater than the V of the ADM6315 input, making it CC suitable for use in more diverse applications ...
