Working Principles

The MAX808MCSA+T is a voltage detector that monitors the supply voltage and provides a reset signal when it falls below a specified threshold. It operates based on a monolithic CMOS circuit, which allows for low power consumption and high accuracy. The threshold voltage can be selected using the TH pin, providing flexibility for different voltage levels. The active-low RESET output indicates when the voltage drops below the threshold, while the MR pin allows for manual control over the reset function.
