Working Principles

LM2903PWR works based on the principle of voltage comparison. It compares the voltages applied to its two input pins (IN+ and IN-) and produces a digital output signal based on the result of the comparison. When the voltage at IN+ is higher than IN-, the output goes low, and when IN- is higher than IN+, the output goes high.
