2. VCC: Supply voltage input
3. TH: Threshold voltage input
4. OUT: Digital output indicating the voltage level

Functional Features

• Monitors the voltage level at the TH pin relative to the supply voltage.
• Provides an active-low open-drain output that goes low when the voltage at TH falls below the threshold voltage.
• The threshold voltage can be adjusted using an external resistor divider network.
• Low quiescent current makes it suitable for battery-powered applications.

Advantages and Disadvantages

Advantages

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

Disadvantages

• Limited to monitoring a single voltage level.
• Requires an external resistor divider network for threshold voltage adjustment.

Working Principles

The MAX6385XS25D4-T operates by comparing the voltage at the TH pin with the internally set threshold voltage. When the voltage at TH falls below the threshold, the output pin (OUT) goes low, indicating a voltage violation. The threshold voltage can be adjusted using an external resistor divider network connected to the TH pin.
