• Fixed reset threshold voltage may not be suitable for all applications.
• Reset timeout period may not be adjustable, limiting flexibility.

Working Principles

The ADM690ANZ is designed to monitor the power supply voltage of electronic systems. It continuously compares the supply voltage with a fixed threshold voltage. When the supply voltage falls below the threshold, the ADM690ANZ generates an active-low reset signal. This signal can be used to reset the system or trigger specific actions.

Detailed Application Field Plans

The ADM690ANZ is commonly used in various electronic systems where reliable operation is crucial. Some typical application fields include:

1. Microcontrollers and microprocessors
2. Industrial control systems
3. Communication equipment
4. Automotive electronics
5. Power management systems

Detailed and Complete Alternative Models

• ADM691AANZ: Similar functionality with adjustable reset threshold voltage.
• ADM693AANZ: Offers additional watchdog timer functionality.
• ADM695AANZ: Provides dual voltage monitoring capability.

(Note: The above alternative models are from the same product family and share similar features.)
