Functional Features

• Monitors the power supply voltage and asserts a reset signal when it falls below the reset threshold.
• Provides a manual reset input for external system reset control.
• Generates an active-low reset output signal to reset the microprocessor or other digital systems.
• Offers a fixed reset timeout period to ensure proper system initialization.

Advantages

• Wide supply voltage range allows compatibility with various power sources.
• Low quiescent current consumption minimizes power dissipation.
• Small package size enables space-efficient integration into electronic designs.
• Reliable reset functionality enhances system stability and reliability.

Disadvantages

• Fixed reset timeout period may not be suitable for all applications requiring different initialization times.
• Limited pin configuration options restrict flexibility in system design.

Working Principles

The ADM8697AN is designed to monitor the power supply voltage and assert a reset signal when it falls below the reset threshold voltage. The reset signal remains active until the power supply voltage rises above the threshold and the reset timeout period elapses. The manual reset input allows external control over the reset function.

Detailed Application Field Plans

The ADM8697AN is commonly used in various electronic systems that require reliable power management and system initialization. Some typical application fields include:

1. Microcontroller-based systems
2. Embedded systems
3. Industrial automation equipment
4. Automotive electronics
5. Medical devices
