Product Overview: ADM697ANZ by Analog Devices Inc.

The ADM697ANZ is a robust, high-performance microprocessor supervisory circuit produced by Analog Devices Inc., a leader in the semiconductor industry. This device is engineered to ensure reliable operation of microprocessor (µP) systems, providing power supply monitoring, backup battery switchover, and watchdog timer functions. Its primary role is to safeguard the system against erratic behavior during power-up, power-down, and operation under low voltage conditions.

Key Features and Benefits

• Power Monitoring: The ADM697ANZ offers precise power supply monitoring, with a reset output that remains asserted for at least 200ms after VCC has risen above the reset threshold. This ensures the µP has sufficient time to stabilize and initialize properly before operation begins.
• Backup Battery Switchover: In the event of power failure, the device automatically switches to a backup battery, maintaining critical memory and real-time clock operations without interruption.
• Watchdog Timer: With a watchdog timer, the ADM697ANZ helps prevent system failures by resetting the µP if it fails to strobe within a preset timeout period, indicating a system malfunction or software lock-up.
• Low Power Consumption: Designed for energy efficiency, the device operates with a low supply current, making it ideal for power-sensitive applications.
• Manual Reset Input: The inclusion of a manual reset input allows for an external trigger to reset the system, providing additional control and safety mechanisms.

Applications

The ADM697ANZ is versatile and can be used in a wide range of applications, including:

• Microprocessor systems
• Computers and computer peripherals
• Embedded systems
• Industrial controllers
• Intelligent instruments

Reliability and Compliance

Analog Devices Inc. is known for its commitment to quality, and the ADM697ANZ is no exception. It is designed to meet stringent industry standards, ensuring reliability and performance in even the most demanding conditions. The device is available in an 18-lead PDIP (Plastic Dual In-line Package) and is specified over the commercial temperature range of 0°C to +70°C.

With its combination of power monitoring, battery backup, and system reset capabilities, the ADM697ANZ is an essential component for enhancing system reliability and preventing data loss in critical applications.
