Functional Features

• Monitors the input voltage and compares it with the threshold voltage set by the user.
• Provides a digital output signal indicating whether the input voltage is above or below the threshold.
• Offers an adjustable threshold voltage to suit various applications.
• Low quiescent current makes it suitable for battery-powered devices.
• Active-low reset output can be used to trigger system resets.

Advantages and Disadvantages

Advantages

• Wide supply voltage range allows compatibility with different power sources.
• Adjustable threshold voltage provides flexibility in voltage monitoring.
• Low quiescent current minimizes power consumption.
• Small package size enables space-saving designs.
• Active-low reset output simplifies system reset implementation.

Disadvantages

• Limited threshold voltage resolution (100mV steps).
• Not suitable for high-voltage applications (limited to 5.5V).

Working Principles

The MAX6385XS16D2-T operates by comparing the input voltage with the threshold voltage set by the user using the SET pin. 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 active-low RESET pin can be connected to a microcontroller or other logic circuitry to trigger a system reset when necessary.
