ADM706RAR

The ADM706RAR from Analog Devices is a microprocessor supervisory circuit designed to monitor power supply conditions and ensure system reliability. It features a precise voltage threshold of 2.63V, triggering an active low reset signal when the supply voltage falls below this level. The reset signal has a minimum timeout of 160ms, providing a stable reset pulse during power-up, power-down, or brownout conditions.

This supervisor IC is suitable for 3V and 3.3V power supply monitoring. It includes a debounced manual reset input and an independent watchdog timer with a 1.6-second timeout. The device also incorporates a 1.25V threshold detector for power fail warnings or low battery detection. Its output is push-pull, totem pole type, facilitating easy integration into digital systems.

The ADM706RAR is supplied in a standard 8-pin SOIC package, designed for surface mounting. Its operating temperature range is -40°C to 85°C, making it suitable for various industrial applications. The low quiescent current of 100µA contributes to power-efficient operation.

This component is ideal for applications requiring critical microprocessor monitoring, such as in computers, controllers, intelligent instruments, battery-operated devices, and portable instruments. It helps prevent code execution errors and ensures correct system initialization and recovery from power disturbances.
