Manufactured by Analog Devices Inc., the ADM695AN is a robust supervisory circuit designed to monitor power supplies in microprocessor systems. It provides a crucial function in ensuring system reliability and preventing data corruption during power failures or brown-out conditions. The ADM695AN offers a range of features tailored to maintain system integrity during adverse power conditions.

Key Features

• Power Monitoring: The ADM695AN supervises +5V power supplies, with precision voltage monitoring that guarantees your system operates within safe voltage levels.
• Reset Output: It features a reset output that remains asserted for at least 200ms after VCC has returned to an acceptable level, providing ample time for the system to stabilize before the processor resumes operation.
• Watchdog Timer: An onboard watchdog timer ensures that the microprocessor does not hang in a runaway or an unresponsive state. If the watchdog timer is not periodically reset by the microprocessor, the ADM695AN will issue a system reset.
• Manual Reset: The device includes a manual reset input that allows for a reset to be triggered with an external pushbutton or logic signal.
• Fail-Safe Power Failure Warning: The ADM695AN provides an early warning of impending power failure, allowing the system to execute shutdown procedures to prevent data loss or corruption.

Applications

The ADM695AN is versatile and can be employed in a variety of applications that require reliable voltage monitoring and system reset functionality. It is particularly useful in:

• Microprocessor Systems
• Computers and Servers
• Industrial Controls
• Intelligent Instruments
• Portable/Battery-Powered Equipment

Technical Specifications

The ADM695AN operates over a temperature range of -40°C to +85°C and is available in an 8-pin DIP package. It is designed to monitor a +5V power supply and has a reset threshold typically set at 4.65V, ensuring reliable operation under specified conditions.
