---

| | --| VDD GND |-- Pin 1: Ground (GND) --| RST OUT |-- Pin 2: Output (OUT) --| TH MR |-- Pin 3: Manual Reset (MR) --| VDD GND |-- Pin 4: Ground (GND) --| RST OUT |-- Pin 5: Output (OUT) --| TH MR |-- Pin 6: Threshold (TH) |___________| ```

Functional Features

• Monitors the input voltage and provides a reset signal when it falls below the threshold voltage.
• Offers manual reset capability through the MR pin.
• Provides an active-low reset output signal.
• Includes a built-in glitch immunity circuit to prevent false triggering.
• Low quiescent current consumption makes it suitable for battery-powered applications.

Advantages and Disadvantages

Advantages: - Wide operating voltage range allows compatibility with various power supply systems. - Small package size enables space-saving designs. - High accuracy ensures reliable voltage monitoring. - Low-power consumption prolongs battery life in portable devices.

Disadvantages: - Limited threshold voltage options may not cover all voltage monitoring requirements. - Reset timeout period may not be adjustable, limiting flexibility in certain applications.

Working Principles

The MAX6720AUTTGD3+T operates by comparing the input voltage with the threshold voltage set by the TH pin. When the input voltage falls below the threshold voltage, the reset output is activated, indicating a low-voltage condition. The reset signal remains active until the input voltage rises above the threshold voltage or a manual reset is triggered through the MR pin.
