Working Principles

The S-80939CLNB-G69T2G operates by comparing the input voltage (RESET IN) with an internal reference voltage. When the input voltage drops below the detection threshold, the reset output (RESET OUT) is activated, pulling it low. This signal can be used to trigger a system reset or perform other necessary actions.
