Working Principles

The ADM696ARZ operates by continuously monitoring the power supply voltage. When the voltage falls below the set threshold, it triggers a reset signal. This signal remains active until the voltage rises above the threshold and the reset timeout period elapses. The device ensures stable system operation during power-up and power-down sequences, preventing data corruption or erratic behavior.
