Working Principles

The TLC3702IDG4 operates based on the principle of comparing two input voltages. It internally generates a reference voltage against which the input voltages are compared. If the voltage at the non-inverting input (IN(+)) is higher than the voltage at the inverting input (IN(-)), the output (OUT) goes high. Conversely, if the voltage at IN(+) is lower than the voltage at IN(-), the output goes low. This behavior allows the IC to detect voltage levels accurately.
