Working Principles

The MAX16030TG+T operates by continuously monitoring the system voltage and comparing it to a reference threshold. If the voltage falls below the threshold, the reset output is activated, indicating a fault condition. The manual reset input allows for external control of the reset function. Additionally, the integrated watchdog timer monitors system activity and resets the system if no activity is detected within the specified timeout period.
