ADM809SARTZ-REEL Microprocessor Supervisory Circuit

The ADM809SARTZ-REEL is a state-of-the-art supervisory circuit designed and manufactured by Analog Devices Inc., a leader in high-performance semiconductors. This compact and efficient device is engineered to monitor power supplies in microprocessor systems, providing a reliable safeguard against system failures due to unstable or failing power conditions.

The ADM809SARTZ-REEL is a vital component for ensuring the integrity and stability of electronic systems. It is designed to assert a reset signal whenever the V<sub>CC supply voltage declines below a preset threshold, maintaining the reset condition for at least 140 ms after V<sub>CC has risen above the reset threshold, ensuring a proper system reset. This feature is crucial for allowing the power supply and processor to stabilize before normal operation resumes.

With its low power consumption, this supervisory circuit is an excellent choice for power-sensitive applications. It operates over a wide supply range and offers a choice of reset threshold voltages, making it versatile for various applications. The ADM809SARTZ-REEL is available in a compact SOT-23 package, which is ideal for space-constrained applications.

Key features of the ADM809SARTZ-REEL include:

• Automatic reset generation on power-up
• Low power consumption
• Guaranteed reset output down to V<sub>CC = 1.0 V
• Power supply glitch immunity
• Watchdog timer with a 1.6-second timeout (ADM809)
• Wide operating temperature range
• RoHS compliant and lead-free component

This product is supplied in a reel, making it suitable for automated mass production environments, where efficiency and reliability in component placement are crucial. The ADM809SARTZ-REEL is an excellent choice for managing power supply conditions in a variety of electronic applications, including computers, controllers, intelligent instruments, and portable electronics, where maintaining the correct operation of the microprocessor is essential for performance and safety.

By integrating the ADM809SARTZ-REEL into your system, you can ensure that your applications run smoothly, even in the face of unpredictable power supply conditions. Analog Devices Inc. provides comprehensive technical support and documentation, making the integration of this supervisory circuit into your design project straightforward and reliable.
