ADM707ARZ-REEL

Supervisors Overview

The ADM707ARZ-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc., designed as a microprocessor reset generator. It operates within a supply voltage range up to 5.5 V and features a fixed threshold voltage of 4.65 V for power monitoring. The device provides a push-pull output with active-high reset logic and includes a manual reset input. It ensures system stability with a minimum reset delay time of 160 ms and a standard reset pulse width of 200 ms. The component supports surface-mount installation in an 8-SOIC package, suitable for industrial temperature ranges from -40°C to +85°C.

Supervisors Feature Summary

• Monitors single power supply input against a precise 4.65 V threshold to detect under-voltage conditions.
• Generates active-high reset signals with configurable push-pull output structure for direct interface compatibility.
• Includes debounced manual reset input allowing external triggering of system reset sequences independent of voltage levels.

Supervisors Applications

• Microprocessor system power supervision
• Controller board voltage monitoring
• Smart instrument reset generation

Supervisors Procurement Notes

Verify the specific suffix REEL indicates tape-and-reel packaging configuration distinct from tube variants. Confirm the 8-SOIC footprint matches design constraints. Check current lifecycle status as end-of-life products may have limited availability or require alternative sourcing strategies for production continuity.

Supervisors Selection Notes

Select this component when a fixed 4.65 V threshold is required for 5 V systems. Choose over ADM706/ADM708 variants if active-high logic is preferred over active-low or if watchdog timer functionality is unnecessary. Ensure SOIC-8 package compatibility with automated assembly processes.

Supervisors Part Context

Part of the ADM705/ADM706/ADM707/ADM708 series of simple reset circuits. Unlike ADM705/ADM706, it lacks an integrated watchdog timer. It serves as a cost-effective solution for basic power monitoring where complex sequencing or multiple thresholds are not required.

Supervisors Replacement Considerations

Cross-reference with ADM707ANZ for through-hole DIP-8 equivalent. Verify functional pinout compatibility with ADM707ARZ non-reel variants before substitution.

Supervisors FAQ

Does the ADM707ARZ-REEL include a watchdog timer?

No, the ADM707 variant does not include a watchdog timer; this feature is reserved for the ADM705 and ADM706 models in the same series.

What is the reset output polarity?

The ADM707 generates an active-high reset signal, meaning the output goes high when the monitored voltage drops below the threshold.
