Working Principles

ADM1232ARN operates by continuously monitoring the supply voltage. When the voltage falls below the programmable threshold, it generates a reset signal to initiate system reset. The reset signal remains active until the supply voltage rises above the threshold and the programmable delay period elapses.

The manual reset input allows for an immediate system reset when activated. This input is typically used during system testing or debugging.
