ADM809RART-REEL7 - Microprocessor Supervisory Circuit

The ADM809RART-REEL7 from Analog Devices Inc. is a highly reliable microprocessor supervisory circuit that provides excellent circuit monitoring functionality for microprocessors (µP) and digital systems. It is designed to maintain system integrity and prevent data corruption during power failures or unexpected system shutdowns. This component is particularly suitable for portable and space-constrained applications due to its small size and power efficiency.

This supervisory circuit is available in a compact SOT-23 package, making it an ideal choice for use in systems where board space is at a premium. The ADM809RART-REEL7 is part of the REEL7 packaging series, indicating that it is provided in tape and reel form for automated assembly processes, facilitating efficient manufacturing and handling.

Key features of the ADM809RART-REEL7 include:

• Power Supply Monitoring: It monitors the power supply voltage and keeps the microprocessor in reset until the system voltage exceeds the reset threshold level. After surpassing this level, the reset signal is kept active for a specified period to allow the system power supply and processor to stabilize.
• Manual Reset Input: An additional feature is the manual reset input that allows for a system reset to be initiated by an external signal, providing further control to the system operator.
• Low Power Consumption: The device operates with very low power consumption, making it suitable for battery-powered applications where power efficiency is critical.
• Reset Threshold Options: The ADM809 series offers several reset threshold options. The specific threshold for the ADM809RART-REEL7 can be found in the manufacturer's datasheet, which allows designers to select the appropriate voltage level for their system requirements.
• Reset Output Stage: The reset output stage can be either push-pull or open-drain, depending on the specific needs of the application, providing flexibility in system design.

The ADM809RART-REEL7 is designed to support a wide range of microprocessor and digital system applications, including computers, controllers, intelligent instruments, and portable electronics. Its robust feature set ensures that it can help maintain the reliability and stability of these systems even in the face of power supply variability or failure.
