Working Principles

The MAX6365LKA26-T is designed to monitor the voltage level of a power supply. It compares the input voltage with an internally generated reference voltage. When the input voltage falls below the threshold voltage set by the user, the output pin goes low, indicating a power failure or an out-of-range condition.

The threshold voltage can be adjusted using an external resistor divider connected to the TH pin. This allows the device to be configured for different voltage levels, making it versatile for various applications.
