Working Principles

The MAX6719UTTZD1+T is a voltage monitor IC that compares the input voltage with a user-defined threshold voltage. It operates by continuously monitoring the voltage level at the TH pin. When the input voltage exceeds the threshold voltage, the output (OUT) goes low, indicating an under-voltage condition. Conversely, when the input voltage falls below the threshold, the output goes high, indicating a normal voltage level.

The threshold voltage can be adjusted by connecting external resistors to the TH pin. This allows customization of the threshold to suit specific application requirements.
