Working Principles

The MAX6365PKA44+T operates by comparing the input voltage (VDD) with the user-adjustable threshold voltage (TH). When the input voltage drops below the threshold, the RESET# pin is pulled low, indicating a low-voltage condition. The MR# pin can be used to manually reset the device. The CT pin is used to adjust the threshold voltage by connecting an external resistor and capacitor.
