3. TH: Threshold voltage adjustment pin
4. RESET: Active-low reset output
5. NC: No connection (leave unconnected)

Functional Features

• Monitors the input voltage and compares it with the threshold voltage set by the user.
• When the input voltage falls below the threshold, the RESET pin is pulled low, indicating a reset condition.
• The threshold voltage can be adjusted using an external resistor divider connected to the TH pin.
• Provides a precise and reliable digital output for voltage monitoring applications.

Advantages and Disadvantages

Advantages

• Wide supply voltage range allows compatibility with various systems.
• Adjustable threshold voltage provides flexibility for different voltage monitoring requirements.
• Low quiescent current ensures minimal power consumption.
• Accurate voltage monitoring with a small tolerance.

Disadvantages

• Limited number of threshold voltage options (100mV steps).
• Open-drain output requires an external pull-up resistor for proper signal interpretation.

Working Principles

The MAX6385XS20D1-T operates by comparing the input voltage with the threshold voltage set by the user. The threshold voltage can be adjusted using an external resistor divider connected to the TH pin. When the input voltage falls below the threshold, the RESET pin is pulled low, indicating a reset condition. The device continuously monitors the voltage and updates the output accordingly.
