Working Principles

ADM1232ARMZ-REEL operates by continuously monitoring the supply voltage using an internal voltage comparator. When the voltage falls below the programmable threshold, the reset output is activated, triggering a system reset. The timeout function ensures that if the voltage remains below the threshold for a programmable period, the timeout output is activated. The manual reset input allows for an external reset signal to override the voltage monitoring function.
