ADM706SAN

Supervisors Overview

The ADM706SAN is a microprocessor supervisory circuit designed for monitoring 3 V or 3.3 V power supplies in through-hole applications. It features a precision voltage monitor with a threshold of 2.93 V and an active low push-pull reset output. The device includes a debounced manual reset input and an independent watchdog timer with a 1.6-second timeout. Operating within a supply voltage range up to 5.5 V, it ensures system reliability with a reset pulse width of 280 ms and operates across temperatures from -40°C to +85°C.

Supervisors Feature Summary

• Integrates a precision voltage monitor with a fixed 2.93 V threshold for accurate supply supervision
• Includes an independent watchdog timer with a 1.6-second timeout to detect software failures
• Features a debounced manual reset input allowing user-initiated system resets
• Provides an active low push-pull reset output compatible with various logic families

Supervisors Applications

• Microprocessor systems requiring reliable power supervision
• Controllers and intelligent instruments needing critical monitoring
• Battery-operated systems utilizing low quiescent current
• Portable instruments demanding compact supervisory solutions

Supervisors Procurement Notes

Verify component authenticity due to discontinued status. Confirm package integrity as DIP-8 units may be surplus. Check datasheet revisions for parameter consistency. Ensure compatibility with existing PCB footprints. Validate supplier authorization for legacy Analog Devices inventory.

Supervisors Selection Notes

Select this part for 3 V or 3.3 V rail monitoring where through-hole mounting is required. Compare against ADM706PANZ for active high outputs or ADM706TANZ for higher thresholds. Consider the ADM708 series if both power-fail and reset functions are needed simultaneously. Verify that the 1.6-second watchdog timeout meets system timing requirements.

Supervisors Part Context

Part of the ADM706/ADM708 family of microprocessor supervisory circuits from Analog Devices. Designed as a superior upgrade for Maxim Integrated MAX706/MAX708 series components. Offers enhanced performance over previous generations with improved accuracy and integrated watchdog functionality for robust system protection.

Supervisors Replacement Considerations

Direct pin-compatible substitutes include ADM706SARZ (SOIC-8) and ADM706SANZ (DIP-8). Verify that replacement packages match board layout constraints. Ensure electrical parameters such as threshold voltage and reset polarity remain identical for seamless integration.
