Working Principles

The MAX1232CSA+TG002 operates by monitoring the supply voltage and generating a reset signal when necessary. It compares the monitored voltage with a precision reference and triggers a reset if the voltage falls below a certain threshold. The watchdog timer continuously monitors the system's activity, and if no activity is detected within the set timeout period, it generates a reset signal. The manual reset input allows for an immediate system reset when triggered.
