Working Principles

The LM8364BALMFX20/NOPB monitors the power supply voltage using an internal voltage reference and comparator circuit. When the voltage drops below the specified threshold, the IC generates a reset signal on the RESET pin. This signal remains active until the voltage rises above the threshold or a manual reset is applied through the MR pin. The reset timeout period ensures that the system remains in a reset state for a sufficient duration during power-up.
