Working Principles

The TL3474AIPWE4 operates as a voltage comparator by comparing the voltages at its IN(+) and IN(-) inputs. When the voltage at IN(+) is higher than the voltage at IN(-), the output (OUT) goes high, indicating a positive comparison. Conversely, when the voltage at IN(-) is higher, the output goes low, indicating a negative comparison. The STROBE pin can be used to disable the output, allowing for control over the comparator's functionality.
