ADM812MARTZ-REEL by Analog Devices Inc.

The ADM812MARTZ-REEL is a high-performance microprocessor supervisory circuit from the renowned manufacturer Analog Devices Inc. This device is designed to monitor the power supply voltage of digital systems, ensuring that the microprocessor and other critical system components are reset properly during power-up, power-down, and brown-out conditions. It is an essential component for any system that requires a reliable operation over a wide range of supply voltages and environmental conditions.

Contained in a compact SOT-23 package, the ADM812MARTZ-REEL is part of a product series that offers different reset threshold levels suitable for a variety of applications. This particular model ensures that systems using a 3.3V power supply can maintain proper functionality by providing a precise voltage threshold monitoring feature. When the monitored voltage drops below the factory-set threshold level, the device asserts a reset signal that remains active until the voltage recovers and stabilizes above the threshold, plus a certain reset timeout period.

The reset output from the ADM812 is typically active-low, which is compatible with most microprocessors and microcontrollers. This makes the device a versatile choice for a wide range of digital systems, from simple consumer electronics to complex industrial controllers. The ADM812MARTZ-REEL also includes a manual reset input, which allows for a system reset to be initiated by an external signal, providing additional flexibility and control for system designers.

Moreover, this supervisory circuit is supplied on a reel, making it suitable for automated assembly processes, and is designed to operate over the extended temperature range of -40°C to +85°C. This temperature range, along with the device's low power consumption and high accuracy, makes the ADM812MARTZ-REEL an excellent choice for portable and battery-powered applications, as well as for harsh industrial environments where reliability is paramount.

In summary, the ADM812MARTZ-REEL from Analog Devices Inc. is a reliable and precise voltage monitoring solution that enhances system stability and safety by ensuring proper reset functionality. Its small footprint, ease of integration, and robust performance make it an ideal choice for a wide array of electronic systems.
