Functional Features

1. Voltage Monitoring: The MAX6368LKA31-T continuously monitors the input voltage and compares it with the user-adjustable threshold voltage.
2. Adjustable Threshold: The threshold voltage can be set using external resistors, allowing flexibility in defining the desired voltage level for triggering an output.
3. Digital Output: The IC provides an active-low open-drain output that indicates when the input voltage falls below the set threshold.
4. Low Power Consumption: With a quiescent current of only 1µA, the MAX6368LKA31-T is designed for low-power applications.

Advantages and Disadvantages

Advantages

• Wide supply voltage range allows compatibility with various systems.
• Adjustable threshold voltage provides flexibility in voltage monitoring applications.
• Low quiescent current minimizes power consumption.
• Small SOT23-3 package enables space-saving designs.

Disadvantages

• Limited pin configuration options due to the three-pin package.
• Accuracy may vary depending on external factors such as temperature and component tolerances.

Working Principles

The MAX6368LKA31-T operates by comparing the input voltage with the threshold voltage set by the user. When the input voltage falls below the threshold, the output becomes active-low, indicating a voltage violation. The threshold voltage can be adjusted using external resistors connected to the V+ and GND pins.
