ADM8699ANZ Microprocessor Supervisory Circuit

The ADM8699ANZ is a high-precision microprocessor supervisory circuit produced by Analog Devices Inc., a renowned leader in the semiconductor industry. This innovative component is designed to monitor the power supply and other critical system functions in microprocessor-controlled systems. It ensures that the microprocessor is reset to a known state during power-up, power-down, and brownout conditions.

Key Features

• Voltage Monitoring: The ADM8699ANZ provides accurate monitoring of power supplies, ensuring that the system operates within the specified voltage thresholds for optimal performance and reliability.
• Power-On Reset: It generates a reset pulse when the supply voltage falls below a preset threshold, enabling the microprocessor to start up in a controlled and predictable manner.
• Manual Reset: An external manual reset input allows for a system reset to be initiated by external hardware or software, providing additional flexibility and control to the system designer.
• Battery Backup Switching: The device includes an automatic backup battery switchover function that preserves memory contents when the main power supply fails.
• Low Power Consumption: With its low power design, the ADM8699ANZ is suitable for power-sensitive applications, ensuring minimal impact on overall system power budgets.
• Watchdog Timer: An on-board watchdog timer can be used to monitor software execution integrity, resetting the system automatically if the software fails to refresh the watchdog within a preset timeout period.
