Working Principles

The MAX6314US31D1+T operates by continuously monitoring the input voltage using an internal voltage reference. 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 microcontrollers, digital logic circuits, or other components in the system. The MR pin provides a manual reset option, allowing the user to initiate a reset manually if needed. The reset timeout period can be adjusted or fixed, depending on the specific model.
