Working Principles

The MAX6388XS21D5-T operates by continuously monitoring the voltage level of the power supply connected to the VCC pin. When the voltage falls below the selected threshold, the IC generates a reset signal on the RESET pin. This signal can be used to reset the microcontroller or other components in the system, ensuring proper initialization.

The reset timeout period can be adjusted using external components connected to the TH pin. This allows customization of the time delay between the power supply voltage dropping below the threshold and the generation of the reset signal.
