Working Principles

The MAX6314US29D2+T is a voltage supervisor IC that continuously monitors the supply voltage. It compares the voltage level with the selected threshold voltage and generates a reset signal when the voltage falls below this threshold. The reset output remains asserted until the voltage rises above the threshold or a manual reset input is triggered. The reset timeout period can be adjusted or fixed, allowing customization based on system requirements.
