Working Principles

The TPS3808G25DBVR is a voltage supervisor IC that monitors the supply voltage and provides a reset signal when the voltage falls below a certain threshold. It ensures proper system operation by preventing erratic behavior during power-up and power-down conditions.

The device continuously compares the supply voltage with the internally set threshold voltage. When the supply voltage drops below the threshold, the reset output is asserted, indicating a power failure or an out-of-range condition. The reset output remains active until the supply voltage rises above the threshold and stabilizes.
