Product Overview: ADM698ARZ by Analog Devices Inc.

The ADM698ARZ is a high-performance supervisory circuit manufactured by Analog Devices Inc., designed to monitor power supplies in microprocessor systems. It provides a precise method to manage power-on reset and power failure warning functions to ensure that the microprocessor is reset to a known state during power-up, power-down, or brown-out conditions.

Key Features:

• Power Supply Monitoring: The device is capable of monitoring +5V power supplies with a precision threshold of 4.65V, ensuring reliable system operation by detecting out-of-tolerance power supply conditions.
• Reset Output: The ADM698ARZ offers an active low reset output, which remains asserted for at least 200ms after the power supply has returned to a stable operating condition, providing ample time for the system to stabilize before the processor starts executing code.
• Battery Backup Switching: It includes an automatic battery backup switching feature that enables the retention of RAM and register data when the system power fails.
• Low Power Consumption: The device is designed for low power consumption, making it ideal for power-sensitive applications.
• Watchdog Timer: An onboard watchdog timer can be used to monitor the microprocessor, ensuring it operates within the application's parameters.
• Compact Package: Packaged in a compact 8-lead SOIC, the ADM698ARZ saves valuable board space in space-constrained applications.

Applications:

The ADM698ARZ is versatile and can be used in a variety of applications, including:

• Microprocessor systems
• Computers
• Controllers
• Intelligent instruments
• Portable equipment

Product Specifications:

With a wide operating temperature range of -40°C to +85°C, the ADM698ARZ is suitable for industrial environments. The device operates from a supply voltage ranging from 4.5V to 5.5V, making it compatible with standard +5V power supplies.

Conclusion:

The ADM698ARZ from Analog Devices Inc. is a robust and reliable solution for power supply monitoring and processor supervision. Its integration of multiple supervisory functions into one package makes it an efficient choice for designers looking to enhance system reliability and reduce component count in their designs.
