Working Principles

The TPS3808G09DBVR operates by continuously monitoring the supply voltage. When the voltage falls below the programmed threshold, the reset output is asserted low, indicating a system reset condition. The reset output remains low until the supply voltage rises above the threshold and the adjustable time delay elapses. The manual reset input allows for an immediate reset regardless of the voltage level.
