Working Principles

The TLV3402IDG4 is a voltage comparator that compares the voltages at its two inputs, IN+ and IN-. It amplifies the voltage difference between these inputs and produces a digital output based on the comparison result. The open-drain output can be pulled low when the voltage at IN- is higher than IN+, and it remains high otherwise.
