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.
