Working Principles

The MAX6367LKA44+ operates by continuously monitoring the supply voltage at the VDD pin. It compares the voltage against the user-defined threshold voltage, which is set using external resistors. When the supply voltage drops below the threshold voltage, the internal comparator triggers the reset output pin (RESET), generating a reset signal. This signal can be used to initiate a system reset or perform other necessary actions to ensure proper functioning of the digital circuitry.
