ADM692AARN-REEL

Supervisors Overview

The ADM692AARN-REEL is a microprocessor supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 4.5 V to 5.5 V and features a fixed reset threshold voltage of 4.4 V. The device provides an active low push-pull output with a timeout delay of 50 ms. It integrates a watchdog timer, power-fail warning, and backup battery switchover functionality. The component is housed in an SOIC-8 package and supports operation temperatures from -40°C to +85°C.

Supervisors Feature Summary

• Integrates precision voltage monitoring with a fixed 4.4 V threshold for reliable system supervision.
• Includes a built-in watchdog timer to detect software malfunctions and ensure processor integrity.
• Provides automatic backup battery switchover to maintain data retention during primary power loss.

Supervisors Applications

• Microprocessor system reset generation
• Battery backup power management
• Watchdog timer implementation

Supervisors Procurement Notes

Verify the specific suffix 'REEL' indicates tape-and-reel packaging rather than tube packaging when sourcing. Confirm RoHS compliance status as legacy variants may differ. Check current lifecycle status as older ADM692 series parts may be discontinued or subject to last-time buys. Ensure the active low output polarity matches the target microprocessor input requirements.

Supervisors Selection Notes

Select this component when a fixed 4.4 V threshold is required for 5 V logic systems. The active low output suits processors expecting a low-active reset signal. Verify that the 50 ms timeout delay meets the system's startup timing constraints. Consider the integrated watchdog and battery switchover if space-saving and reduced external component count are priorities.

Supervisors Part Context

This part belongs to the ADM692A family of CMOS supervisory circuits designed for 5 V applications. It shares functional similarities with the ADM690A and ADM691A but differs in reset threshold voltage and output configuration. The REEL suffix denotes reel packaging for automated assembly processes.

Supervisors Replacement Considerations

ADM692AARNZ-REEL: Direct equivalent with RoHS-compliant lead finish. MAX692AESA+: Pin-compatible alternative with similar features but different reset timeout characteristics.
