Working Principles

The MAX6383XR24D2-T operates by continuously monitoring the voltage level of the power supply connected to its VCC pin. When the voltage falls below the selected threshold voltage (determined by the TH pin), the IC generates an active-low reset signal on the RESET pin. This reset signal can be used to initiate a system reset or trigger other necessary actions.
