Working Principles

The MAX6313UK39D2-T operates by continuously monitoring the supply voltage connected to the VCC pin. When the voltage falls below the selected threshold voltage (set using the TH pin), the IC generates a reset signal on the RESET pin. This signal can be used to reset the microcontroller or other system components.

The manual reset input (MR pin) allows for an immediate system reset, overriding the voltage monitoring function. The reset timeout period determines how long the reset signal remains active after the voltage returns above the threshold level. It can be set to a fixed value or adjusted using an external capacitor.
