4. VCC: Positive supply voltage input

Functional Features

• Voltage Monitoring: The MAX637ACSA+ continuously monitors the input voltage and compares it with the threshold voltage set by the TRIP pin.
• Threshold Detection: When the input voltage falls below the threshold voltage, the RESET pin is pulled low, indicating a voltage violation.
• Precision Comparator: The built-in comparator ensures accurate voltage monitoring and detection.
• Open-Drain Output: The active-low open-drain output allows for flexible interfacing with other devices.

Advantages and Disadvantages

Advantages
