The ADM696AN is a robust microprocessor supervisory circuit designed and manufactured by Analog Devices Inc., a leader in high-performance semiconductors. This product is engineered to monitor the power supply and microprocessor activity in digital systems, providing a crucial layer of protection against system failures caused by power anomalies or processor malfunctions.

Key Features

• Power Supply Monitoring: The ADM696AN keeps a vigilant eye on the power supply, ensuring that the voltage levels remain within the acceptable range for reliable system operation. It triggers a system reset when it detects an out-of-tolerance power supply condition.
• Microprocessor Monitoring: This device monitors the microprocessor, watching for signs of activity such as clock signals. In the event of a processor hang-up or software failure, the ADM696AN can initiate a reset to restore normal operations.
• Manual Reset Input: A manual reset input allows for an external trigger to reset the system, providing designers and users with additional control over the system's behavior.
• Backup Battery Switchover: In the event of a primary power failure, the ADM696AN can automatically switch to a backup battery, ensuring uninterrupted operation and data retention.
• Watchdog Timer: The integrated watchdog timer serves as a safeguard against software lock-up, requiring regular interaction from the processor to prevent automatic system reset.
• Fail-Safe Output: The fail-safe output can be used to signal other system components in the event of a detected fault, allowing for coordinated responses to system errors.

Applications

The ADM696AN is versatile and can be used in a variety of applications, including but not limited to:

• Computers and computer peripherals
• Embedded systems
• Industrial controllers
• Intelligent instruments
• Portable and battery-powered equipment
