Working Principles

TLC7725QPG4 operates by comparing the input voltage (IN) with the selected threshold voltage (TH). When the input voltage exceeds the threshold voltage, the open-drain output (OUT) is pulled low, indicating a monitored condition. Conversely, when the input voltage falls below the threshold voltage, the output remains high impedance.

The built-in hysteresis ensures that the output does not oscillate near the threshold voltage due to noise or minor fluctuations. This enhances the stability and reliability of the voltage monitoring process.
