Working Principles

The MAX6897AAZT/V+T is a voltage detector IC that monitors the input voltage and generates a reset signal when it falls below a specified threshold. It operates based on a precise internal voltage reference and comparator circuitry. The threshold voltage can be selected using an external resistor divider network connected to the TH pin. When the input voltage drops below the threshold, the output goes low, indicating a reset condition.
