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

Functional Features

• Monitors the input voltage and compares it with the threshold voltage set by the user.
• Provides a digital output that indicates whether the input voltage is above or below the threshold.
• Adjustable threshold voltage options allow flexibility in monitoring different voltage levels.
• Low quiescent current ensures minimal power consumption.

Advantages and Disadvantages

Advantages

• Wide supply voltage range allows compatibility with various systems.
• Adjustable threshold voltage options provide versatility in voltage monitoring applications.
• Low quiescent current minimizes power consumption, making it suitable for battery-powered devices.
• Small SOT23-3 package enables space-saving integration into compact designs.

Disadvantages

• Limited number of threshold voltage options may not cover all desired voltage levels.
• Lack of built-in hysteresis may result in unstable output when the input voltage is near the threshold.

Working Principles

The MAX6382XR31D3-T operates by comparing the input voltage with the threshold voltage set by the user. When the input voltage exceeds the threshold, the digital output (OUT) goes high. Conversely, when the input voltage falls below the threshold, the output goes low. The adjustable threshold voltage allows customization for specific voltage monitoring requirements.
