ADM809-5LAKSZ-REEL Microprocessor Supervisory Circuit

The ADM809-5LAKSZ-REEL is a state-of-the-art microprocessor supervisory circuit designed and manufactured by Analog Devices Inc., a leader in high-performance analog, mixed-signal, and digital signal processing integrated circuits. This device is specifically engineered to monitor power supplies in microprocessor and digital systems, providing a high degree of precision and reliability.

With its compact SOT-23 package, the ADM809 is ideal for space-constrained applications. It provides a precise 4.63 V power supply monitoring, ensuring that the systems it supervises operate within their specified voltage thresholds. This is crucial for maintaining the integrity and stability of the system's performance, particularly in critical applications where consistent operation is mandatory.

One of the key features of the ADM809-5LAKSZ-REEL is its ability to assert a reset signal whenever the V_CC supply voltage falls below the 4.63 V threshold. The reset output remains asserted for a minimum of 140 ms after V_CC has risen above the reset threshold, providing ample time for the system to stabilize upon power-up or during a brown-out condition. This automatic reset generation ensures that the microprocessor restarts in a known state, which is essential for system recovery and data integrity.

Moreover, the ADM809 offers a low power consumption, making it an excellent choice for portable and battery-powered applications. Its low supply current of 17 μA (typical) helps to extend battery life and reduce overall power consumption, contributing to the efficiency and eco-friendliness of the end product.

The device is available in a 3-pin SOT-23 package, which is not only space-saving but also allows for easy integration into existing designs. The ADM809-5LAKSZ-REEL variant is supplied on a reel, facilitating automated manufacturing processes and ensuring a streamlined production flow for high-volume requirements.

Overall, the ADM809-5LAKSZ-REEL from Analog Devices Inc. represents a robust solution for system voltage monitoring, offering both precision and ease of integration, making it a top choice for designers looking to enhance the reliability and performance of their digital systems.
