Working Principles

The TPS3106E16DBVRG4 operates by continuously monitoring the supply voltage using an internal voltage comparator. When the voltage falls below the programmed threshold, the reset output is activated, indicating a low-voltage condition. The precision voltage reference ensures accurate voltage monitoring.

The watchdog timer function requires a periodic input signal (WDI) to be provided within the specified timeout period. If the input signal is not received within this timeframe, the watchdog timer triggers a system reset.

The manual reset input allows an external signal to initiate a system reset, providing flexibility in system control.
