ADM706RARZ-REEL7

Supervisors Overview

The ADM706RARZ-REEL7 is a voltage monitoring microprocessor supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of up to 5.5 V and features a fixed threshold voltage of 3.0 V for power supply supervision. The device provides a push-pull active-low reset output with a typical reset delay time of 380 ms. It includes an internal watchdog timer with a timeout period of approximately 1.25 seconds, which can be disabled if not required. The component supports manual reset functionality via an external input pin. It is designed for surface-mount installation in an 8-pin SOIC package and complies with RoHS standards.

Supervisors Feature Summary

• Integrated watchdog timer with selectable timeout period for system reliability
• Manual reset input capability for user-initiated system recovery
• Active-low push-pull reset output driver
• Fixed voltage threshold supervision for single-channel monitoring

Supervisors Applications

• Microprocessor power supply monitoring
• Battery-powered system supervision
• Watchdog timer implementation in embedded controllers
• Manual reset circuit integration

Supervisors Procurement Notes

Verify the specific suffix REEL7 indicates tape-and-reel packaging when sourcing. Confirm the manufacturer is Analog Devices Inc., as Rochester Electronics may distribute surplus stock. Ensure the order specifies the correct SOIC-8 package variant. Cross-reference the datasheet revision to confirm feature availability such as the watchdog timer enable state. Validate RoHS compliance status for current production runs.

Supervisors Selection Notes

Select this component when a fixed 3.0 V threshold is appropriate for the target supply rail. The inclusion of a manual reset pin distinguishes it from variants lacking this feature. Consider the 380 ms reset delay against system startup requirements. The integrated watchdog simplifies design compared to discrete solutions. Verify that the 5.5 V maximum supply rating aligns with the application's peak voltage conditions.

Supervisors Part Context

This part belongs to the ADM706 series of supervisory circuits. It shares the core architecture with other suffixes like ADM706ARZ and ADM706SARZ, differing primarily in packaging and minor electrical tolerances. The series is designed for low-power applications requiring reliable power management. Analog Devices positions these components for cost-sensitive consumer and industrial electronics.

Supervisors Replacement Considerations

ADM706ARZ-REEL7 serves as a direct functional substitute with identical electrical characteristics. ADM706SARZ offers similar performance in a different package configuration. Check datasheets for exact threshold voltage tolerances and reset delay variations between revisions.
