Working Principles

The TPS3307-18DGNRG4 operates by continuously monitoring the supply voltage using an internal voltage reference. If the voltage falls below the specified threshold, it triggers the reset output, which can be used to reset the microcontroller or other system components. Additionally, the integrated watchdog timer monitors the system's operation by periodically receiving a watchdog input signal. If this signal is not received within the specified timeout period, the watchdog timer generates a reset signal to ensure the system's integrity.
