ADM706RAR-REEL

Supervisors Overview

The ADM706RAR-REEL is a microprocessor supervisory circuit designed for monitoring 3 V or 3.3 V power supplies in industrial and commercial applications. It features a precision voltage monitor with a typical reset threshold of 2.93 V, ensuring reliable operation within the specified range. The device provides an active low push-pull reset output with a guaranteed reset pulse width of 200 ms. It includes a debounced manual reset input and an independent watchdog timer with a 1.6-second timeout period. Operating from a supply voltage between 1 V and 5.5 V, it draws a maximum quiescent current of 100 μA. The component is available in an 8-pin SOIC package.

Supervisors Feature Summary

• Integrates a precision voltage monitor with a fixed threshold for stable power supervision
• Includes an independent watchdog timer with a 1.6-second timeout to detect software failures
• Features a debounced manual reset input for user-initiated system resets
• Provides an active low push-pull reset output compatible with various logic families

Supervisors Applications

• Microprocessor systems requiring critical power monitoring
• Portable instruments and battery-operated devices
• Industrial controllers and intelligent instruments
• Computers and embedded systems needing watchdog functionality

Supervisors Procurement Notes

Verify the specific suffix REEL indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status as historical data may vary by production batch. Check for obsolescence notices from Analog Devices, as this part number may be discontinued or replaced by newer series. Ensure the supplier provides valid traceability documentation for industrial-grade components.

Supervisors Selection Notes

Select this component when a fixed 3 V threshold is required without programmable options. Compare against ADM706P/S/T variants if different voltage thresholds are needed. Consider the ADM708 series if both active high and active low outputs are necessary. Verify that the 1.6-second watchdog timeout meets the system's fault detection requirements.

Supervisors Part Context

The ADM706RAR-REEL belongs to the ADM706 family of voltage monitoring circuits manufactured by Analog Devices. This family serves as a successor to older MAX706 series parts, offering improved performance and reliability. The RAR variant specifically denotes the active low output configuration in an SOIC package with reel packaging. It is part of a broader portfolio of supervisory ICs designed for robust system management.

Supervisors Replacement Considerations

Public confirmed substitute part numbers include ADM706RARZ for lead-free compliance. Direct functional equivalents in the same family include ADM706PAR and ADM706SAR depending on threshold requirements. Verify pin compatibility before replacing with ADM708 variants due to potential output configuration differences.
