Working Principles

The S-8240AAG-I6T1U operates by continuously monitoring the supply voltage through the VDD pin. If the voltage drops below the detection threshold, the RESET pin is activated, generating a reset signal to the connected microcontroller or digital device. Additionally, the watchdog timer monitors the WDI pin for periodic input from the microcontroller. If no input is received within the specified timeout period, the RESET pin is triggered, resetting the system.
