Functional Features

• Voltage monitoring: The MAX16059ATT28+T continuously monitors the power supply voltage and asserts the reset signal when it falls below the specified threshold.
• Adjustable reset timeout: The reset timeout period can be adjusted according to the application requirements.
• Manual reset input: Allows for external control of the reset signal.
• Watchdog timer: Provides a mechanism to detect and recover from system malfunctions.
• Power-on reset delay: Ensures stable operation during power-up.

Advantages and Disadvantages

Advantages: - Low power consumption. - Precision voltage monitoring. - Adjustable reset timeout period. - Manual reset input for external control. - Watchdog timer for system reliability.

Disadvantages: - Limited operating temperature range (-40°C to +85°C). - Only available in a specific package (28-TDFN).

Working Principles

The MAX16059ATT28+T operates by comparing the power supply voltage with a reference threshold. When the voltage drops below this threshold, the reset signal is asserted. The reset timeout period can be adjusted using external components. The manual reset input allows for additional control over the reset signal. The watchdog timer monitors the system's operation and resets it if necessary. The power-on reset delay ensures stable operation during power-up.

Detailed Application Field Plans

The MAX16059ATT28+T is commonly used in various applications where voltage supervision is critical. Some of the typical application fields include:

1. Microcontrollers: Ensuring proper reset and reliable operation of microcontroller-based systems.
2. Industrial Control Systems: Monitoring power supply voltage in industrial automation and control systems.
3. Automotive Electronics: Voltage supervision in automotive electronic systems for safety and reliability.
4. Battery-Powered Devices: Protecting battery-powered devices from undervoltage conditions.
5. Communication Systems: Voltage monitoring in communication equipment to prevent data corruption.

Detailed and Complete Alternative Models

1. MAX16058ATT28+T: Similar to MAX16059ATT28+T but with a fixed reset timeout period.
2. MAX16060ATT28+T: Voltage supervisor IC with additional features like adjustable reset threshold and power-fail detection.
3. MAX16061ATT28+T: Dual voltage supervisor IC for monitoring two independent power supplies.
