---

| | --| RESET |-- --| GND |-- --| MR |-- --| VCC |-- --| RST |-- --| N.C. |-- --| N.C. |-- |___________| ```

Functional Features

• Monitors the supply voltage and asserts a reset signal when it falls below the specified threshold.
• Provides a debounced reset output that remains asserted for the specified timeout period after the supply voltage rises above the threshold.
• Low quiescent current consumption, making it suitable for battery-powered applications.
• Built-in glitch immunity ensures reliable operation in noisy environments.

Advantages and Disadvantages

Advantages: - High accuracy in monitoring voltage levels. - Wide supply voltage range allows for versatile applications. - Small package size saves board space. - Low power consumption extends battery life.

Disadvantages: - Limited reset threshold and timeout period options. - Not suitable for high-voltage applications.

Working Principles

The MAX16081XR31Q+T operates by continuously monitoring the supply voltage. When the voltage falls below the specified threshold, the reset output is asserted, indicating a power failure or an unstable voltage condition. Once the voltage rises above the threshold, the reset output remains asserted for the specified timeout period to ensure that the system has stabilized before resuming normal operation.

Detailed Application Field Plans

The MAX16081XR31Q+T is commonly used in various applications where reliable voltage monitoring and system reset functionality are required. Some of the typical application fields include:

1. Microcontroller Systems: Provides a reset signal to microcontrollers to ensure proper initialization and prevent erratic behavior during power-up or voltage fluctuations.
2. Industrial Control Systems: Monitors power supply voltages in industrial control systems to prevent data corruption or damage to sensitive equipment during voltage transients.
3. Automotive Electronics: Ensures reliable operation of automotive electronic systems by monitoring the vehicle's power supply and initiating a reset if necessary.
4. Battery-Powered Devices: Protects battery-powered devices from operating at low voltages, preventing potential damage to the system or loss of critical data.
