• Supports battery backup switching mechanisms

Supervisors Applications

• Microprocessor reset circuits
• Power management supervision
• Embedded system monitoring

Supervisors Procurement Notes

This component is marked as obsolete and no longer manufactured by Analog Devices Inc. Verification of availability should focus on existing stock or authorized distributors holding legacy inventory. Direct replacement from the manufacturer is not possible; engineers must evaluate parametric equivalents or updated series components for new designs. Ensure compatibility with existing PCB footprints if utilizing remaining stock.

Supervisors Selection Notes

Designers requiring this specific supervisory function should consider the ADM8696 series or other modern Analog Devices supervisors that offer similar thresholds and package options. Verify that the replacement part supports the required 1.3 V threshold and 50 ms reset delay. Check for updated feature sets such as manual reset inputs or different output configurations that may better suit current application requirements while maintaining pin compatibility.

Supervisors Part Context

The ADM8697 belongs to the ADM86xx family of microprocessor supervisory circuits, designed to monitor voltage levels and ensure proper system startup. It serves as an improved version of earlier ADM696 devices, offering enhanced accuracy and integrated watchdog features. The REEL suffix indicates tape-and-reel packaging for automated assembly processes.

Supervisors Replacement Considerations

Direct substitutes include the ADM8697ARWZ and parametric equivalents like the ADM696ARZ-REEL. Evaluate these parts for pin compatibility and electrical parameter alignment before integration into existing designs.
