Working Principles

The MAX6313UK45D2-T operates by continuously monitoring the supply voltage connected to the VCC pin. When the voltage drops below the threshold voltage set by the TH pin, the IC generates an active-low reset signal on the RESET pin. This signal can be used to reset microcontrollers, digital logic circuits, or other components in the system.

The threshold voltage can be adjusted by connecting an external resistor divider network to the TH pin. This allows customization of the voltage level at which the reset signal is triggered.

Additionally, the MR pin provides a manual reset option. Pulling this pin low forces an immediate reset, regardless of the monitored voltage level.
