Working Principles

The MAX6715UTYHD3+T is a voltage monitor and reset circuit that operates by comparing the supply voltage with a user-selectable threshold voltage. When the supply voltage falls below the threshold, the reset output is activated, indicating a low voltage condition. The reset remains active until the supply voltage rises above the threshold or a manual reset signal is applied to the MR pin. The adjustable reset timeout period allows customization of the time delay before the reset signal is released.
