Working Principles

The LM25066IAPSQE/NOPB works by continuously monitoring the voltage level of a power supply. When the voltage falls below the set threshold, it triggers the internal circuitry to generate a reset signal. This reset signal can be used to initiate a system reset or perform other necessary actions to ensure stable operation.

The device also includes an adjustable timeout period feature, allowing the user to configure the duration for which the reset signal remains active after the voltage returns to normal. This feature prevents false resets caused by temporary voltage fluctuations.
