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.
