Working Principles

The MAX6719UTSHD3+T operates by comparing the input voltage (IN) with the threshold voltage (TH) set by the user. When the input voltage is below the threshold, the output signal (OUT) is pulled low. Conversely, when the input voltage exceeds the threshold, the output signal remains high impedance.

The threshold voltage can be adjusted using an external resistor divider network connected to the TH pin. This allows the user to set the desired voltage level for monitoring.
