• Reset output: The RESET pin provides an active-low output signal when the monitored voltage falls below the threshold, indicating a power supply fault.

Advantages and Disadvantages

Advantages: - Low-power operation extends battery life in portable devices. - Adjustable threshold voltage allows customization for various applications. - Small package size enables space-saving designs.

Disadvantages: - Limited operating temperature range (-40°C to +85°C). - Single threshold voltage adjustment limits flexibility in complex power supply monitoring scenarios.

Working Principles

The MAX6367LKA46+T is based on a voltage comparator circuit. It compares the input voltage with the internally set threshold voltage. When the input voltage drops below the threshold, the RESET pin is pulled low, indicating a power supply fault. The device operates with low quiescent current, ensuring minimal power consumption during normal operation.
