ADM691ARZ-REEL

Supervisors Overview

The ADM691ARZ-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single-input power supplies in microprocessor systems. It operates within a maximum supply voltage of 5.5 V and features a threshold voltage of 4.65 V with an overvoltage threshold of 4.73 V. The device provides an open-drain output, includes a watchdog timer, and supports battery backup switching. It lacks manual reset functionality and has a reset delay time of 200 ms. Operating temperatures range from -40 C to +85 C, and it is housed in an SOIC-16 package.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Supports battery backup switching for continuous operation during power transitions
• Features open-drain output configuration for flexible interfacing

Supervisors Applications

• Microprocessor system supervision
• Power supply monitoring in industrial electronics
• Battery-backed system protection

Supervisors Procurement Notes

Verify component authenticity through official Analog Devices channels or authorized distributors. Confirm the specific suffix matches the required reel packaging format. Check current lifecycle status as end-of-life notifications may affect long-term availability. Ensure RoHS compliance documentation aligns with regional regulatory requirements before integration into production designs.

Supervisors Selection Notes

Select this component when a single-input voltage supervisor with integrated watchdog functionality is required. Consider the open-drain output type for compatibility with existing logic levels. Evaluate the 200 ms reset delay against system startup timing requirements. Verify that the SOIC-16 package fits the available PCB footprint constraints.

Supervisors Part Context

This part belongs to the ADM691 series of supervisory circuits from Analog Devices. It is specifically packaged in a reel format for automated surface-mount assembly processes.
