Working Principles

The S-8240AAN-I6T1U operates by continuously monitoring the power supply voltage connected to the VDD pin. It compares the voltage against a preset detection threshold and generates a reset signal on the RESET pin when the voltage drops below this threshold. The IC also incorporates a watchdog timer that requires a periodic pulse from the microcontroller. If the pulse is not received within the specified timeout period, the IC triggers a reset signal, ensuring system integrity.
