Working Principles

The MAX6385XS27D7-T is designed to monitor voltage levels and provide a digital output based on the threshold set by the user. It operates by comparing the voltage at the TH pin with the internally set threshold voltage. When the voltage at the TH pin drops below the threshold, the RESET pin is pulled low, indicating a reset condition. The threshold voltage can be adjusted externally using a resistor divider network.
