ADM809RAKSZ-REEL Microprocessor Supervisory Circuit from Analog Devices Inc.

The ADM809RAKSZ-REEL is a state-of-the-art microprocessor supervisory circuit that provides excellent power supply monitoring and control for microprocessors (μP) and digital systems. Manufactured by Analog Devices Inc., a leader in the field of high-performance semiconductors, this component is designed to ensure that systems operate reliably and within their power specifications.

This supervisory circuit is particularly suitable for portable, battery-powered applications due to its low power consumption. The device features a reset output during power-up, power-down, and brownout conditions. Upon detection of a fault condition, the ADM809RAKSZ-REEL asserts a reset signal to prevent the microprocessor from executing erroneous instructions, which can lead to data corruption or system malfunctions.

The reset output remains operational with V<sub>CC as low as 1.0 V, which is vital for low-voltage operations. The device boasts a reset threshold voltage of approximately 2.63V, which is suitable for 3V logic families. Additionally, the ADM809RAKSZ-REEL offers a 140 ms minimum power-on reset pulse width, which provides ample time for the system to stabilize before the microprocessor starts to execute code.

Offered in a compact SOT-23 package, the ADM809RAKSZ-REEL is designed for space-constrained applications. Its small footprint and surface-mount packaging make it ideal for modern compact circuit designs. The device is part of the REEL packaging series, indicating it is provided in tape and reel packaging suitable for automated assembly processes, further facilitating efficient manufacturing and scalability.

Analog Devices Inc. ensures high reliability and performance with the ADM809RAKSZ-REEL, making it an excellent choice for designers looking for a robust supervisory solution for their digital systems. Its features make it a versatile component for a wide range of applications, including computers, controllers, intelligent instruments, and portable electronics.

With its precision monitoring capabilities and low power consumption, the ADM809RAKSZ-REEL from Analog Devices Inc. offers a comprehensive solution for system stability and integrity, ensuring that digital systems operate consistently and reliably under various conditions.
