```

---

| | --| VDD | --| GND | --| OUT | --| TH | --| MR | |___________| ```

• VDD: Power supply pin
• GND: Ground pin
• OUT: Digital output pin
• TH: Threshold voltage selection pin
• MR: Manual reset pin

Functional Features

1. Voltage Monitoring: The MAX6721AUTVDD1+T continuously monitors the input voltage and compares it with the threshold voltage set by the TH pin.
2. Digital Output: The device provides an active-low open-drain output that indicates whether the input voltage is above or below the threshold voltage.
3. Manual Reset: The MR pin allows for manual resetting of the device, overriding the voltage monitoring function temporarily.

Advantages and Disadvantages

Advantages: - Low-power consumption - High accuracy - Small form factor - Wide operating voltage range

Disadvantages: - Limited threshold voltage options - Lack of adjustable hysteresis

Working Principles

The MAX6721AUTVDD1+T operates by comparing the input voltage with the threshold voltage set by the TH pin. If the input voltage is below the threshold, the OUT pin is pulled low, indicating a low-voltage condition. Conversely, if the input voltage is above the threshold, the OUT pin remains high, indicating a normal voltage level. The MR pin can be used to manually reset the device, temporarily disabling the voltage monitoring function.

Detailed Application Field Plans

The MAX6721AUTVDD1+T finds applications in various fields, including:

1. Battery-Powered Devices: It can be used to monitor battery voltage levels and trigger actions when the voltage drops below a certain threshold.
2. Power Management Systems: The device can be integrated into power management circuits to ensure stable voltage supply and protect sensitive components from undervoltage conditions.
3. Industrial Control Systems: It can be employed in industrial control systems to monitor critical voltage levels and initiate appropriate actions or alarms in case of deviations.
