Working Principles

The S-80954CLNB-G7QT2G operates by continuously monitoring the input voltage (VDD). When the voltage falls below the detection threshold, the internal delay circuit is triggered. After a specified delay time, the output pin (OUT) switches to a low state, indicating the voltage drop. The open-drain configuration allows easy connection to other devices, such as microcontrollers or logic circuits.
