Working Principles

The TPS3823-30QDBVRQ1 works by continuously monitoring the supply voltage. When the voltage drops below the preset threshold (3.0V), the device triggers a reset signal, indicating a power-on reset condition. The reset output remains active until the supply voltage rises above the threshold and the reset delay time elapses.
