Analog Devices Inc. ADM810RART Microprocessor Supervisory Circuit

The ADM810RART is a robust microprocessor supervisory circuit designed and manufactured by Analog Devices Inc., a leader in high-performance semiconductors. This compact and efficient component is engineered to monitor power supplies in microprocessor and digital systems, providing a high degree of precision and reliability.

Constructed to ensure the stability of system operations, the ADM810RART offers a variety of key features that make it an excellent choice for a wide range of applications. It is equipped with a reset output that remains asserted for a minimum of 140ms after V<sub>CC has risen above the reset threshold level. This feature ensures that the system has sufficient time to stabilize before the processor starts operating.

One of the main advantages of the ADM810RART is its ability to assert a reset signal whenever the V<sub>CC supply voltage declines below a preset threshold, safeguarding the system against brown-out conditions. This is critical for applications that require consistent performance and cannot tolerate data corruption due to unexpected power disturbances.

The device is also notable for its low power consumption, drawing a quiescent current of typically only 17μA. This makes it an ideal choice for power-sensitive applications, including portable and battery-operated devices. The ADM810RART operates over a wide temperature range, from -40°C to +85°C, ensuring reliability in diverse environmental conditions.

The ADM810RART comes in a compact SOT-23 package, which is highly favored for space-constrained applications. Its small footprint does not compromise its performance, and it integrates seamlessly into various circuit designs, providing a high level of protection with minimal additional components.

In summary, the ADM810RART from Analog Devices Inc. is a highly reliable and efficient supervisory circuit that offers crucial protection for microprocessors by monitoring power supplies and ensuring system stability. Its low power consumption, precision voltage monitoring, and compact design make it an excellent choice for a vast array of electronic applications.
