Working Principles

The TPS3824-30QDBVRQ1 operates by monitoring the voltage input threshold (VIT) pin. When the supply voltage (VDD) rises above the preset threshold of 3.0V, the device generates a power-on reset signal. This signal remains active until the supply voltage drops below the threshold or a manual reset (MR) signal is applied.
