Functional Features

• Monitors the input voltage and compares it with the threshold voltage.
• Provides an active-low open-drain output signal when the input voltage falls below the threshold.
• Built-in hysteresis prevents output oscillation near the threshold voltage.
• Low quiescent current makes it suitable for battery-powered applications.
• Wide supply voltage range allows for versatile use in various systems.

Advantages and Disadvantages

Advantages: - High accuracy ensures reliable voltage monitoring. - Low power consumption extends battery life in portable devices. - Small package size saves board space. - Wide supply voltage range provides flexibility in different applications.

Disadvantages: - Limited threshold voltage options may not cover all desired voltage levels. - Active-low open-drain output may require additional circuitry for certain applications.

Working Principles

The MAX8216MJD operates by comparing the input voltage (IN+) with the threshold voltage (TH). When the input voltage falls below the threshold, the output (OUT) becomes active-low, indicating a voltage fault condition. The built-in hysteresis prevents output oscillation near the threshold voltage, ensuring stable operation.
