Working Principles

The TPS3839E16DQNT operates by continuously monitoring the input voltage. When the voltage drops below the preset threshold of 1.6V, the device triggers a reset signal on the RESET OUT pin. This signal indicates that the voltage has fallen below the acceptable level, allowing the connected system to take appropriate action.

The power-on reset delay feature ensures that the reset signal is not triggered immediately upon power-up. This delay allows the system to stabilize before receiving the reset signal, preventing false triggering during power fluctuations.
