Working Principles

The MAX6313UK38D4-T is designed to monitor the supply voltage of a system. It compares the voltage at the TH pin with an internal reference voltage. When the supply voltage drops below the selected threshold, the RESET pin goes low, indicating a reset condition. The reset output remains low until the supply voltage rises above the threshold for the specified timeout period. The MR pin can be used to manually force a reset.
