ADM706AR-REEL7

Supervisors Overview

The ADM706AR-REEL7 is a microprocessor supervisory circuit manufactured by Analog Devices Inc., designed for monitoring 5 V power supplies and batteries. It features a precision voltage monitor with a threshold of 4.40 V and an independent watchdog timer with a 1.60-second timeout. The device provides a manual reset input, a quiescent current of 190 μA, and a reset pulse width of 200 ms. It operates within a temperature range of -40°C to +85°C and is housed in an 8-SOIC package.

Supervisors Feature Summary

• Includes an independent watchdog timer for monitoring microprocessor activity
• Features a debounced manual reset input compatible with TTL/CMOS logic
• Provides guaranteed reset validity at low supply voltages down to 1 V

Supervisors Applications

• Microprocessor systems
• Computers
• Controllers
• Intelligent instruments
• Critical microprocessor supply monitoring

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to limited availability status. Confirm RoHS compliance and specific reel packaging requirements before procurement. Ensure the selected variant matches the required voltage threshold and output polarity specifications for the target application design.

Supervisors Selection Notes

Select this component when a dedicated watchdog timer and precise voltage supervision are required for 5 V systems. Compare against the ADM705, ADM707, and ADM708 variants if different voltage thresholds or active-high outputs are needed. Ensure the 8-SOIC package fits the PCB layout constraints and that the 190 μA quiescent current meets power budget requirements.

Supervisors Part Context

This part belongs to the ADM705/ADM706/ADM707/ADM708 series of low-cost microprocessor supervisory circuits from Analog Devices. These devices serve as superior upgrades for legacy MAX705 to MAX708 components, offering integrated watchdog functionality and precise voltage monitoring in a compact surface-mount package suitable for various industrial and commercial electronics.
