ADM693AARNZ-REEL

Supervisors Overview

The ADM693AARNZ-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single-input power supplies in CMOS applications. It operates within a maximum supply voltage of 5.5 V and features a threshold voltage of 4.4 V with an overvoltage threshold of 4.5 V. The device provides open-drain and push-pull outputs, includes a watchdog timer, battery backup switch, and chip enable signal. It has a reset delay time of 280 ms and consumes 100 uA of operating current. Packaged in SOIC-16 on a reel, it functions between -40 C and +85 C.

Supervisors Feature Summary

• Integrates watchdog timer functionality for system reliability
• Supports battery backup switching capabilities
• Includes chip enable signal control

Supervisors Applications

• CMOS process integrated circuits
• Voltage supervision systems
• Power management ICs

Supervisors Procurement Notes

Verify component authenticity through official Analog Devices channels or authorized distributors. Confirm the specific suffix indicates reel packaging. Check for obsolescence status as some variants may be end-of-life. Ensure environmental compliance documentation matches project requirements. Validate package type against design constraints before procurement.

Supervisors Selection Notes

Select this component when a single-input voltage supervisor with both open-drain and push-pull outputs is required. Consider the 280 ms reset delay and 100 uA current consumption for low-power designs. Verify that the 4.4 V threshold aligns with the target supply rail. Ensure the SOIC-16 package fits the PCB layout. Confirm temperature range suitability for the operating environment.

Supervisors Part Context

This part belongs to the ADM693A series of supervisory circuits from Analog Devices. It is related to other models like ADM693AARWZ which shares similar electrical characteristics but differs in packaging format. The series focuses on providing reliable power management solutions for embedded systems requiring precise voltage monitoring and reset generation.

Supervisors Replacement Considerations

ADM693AARWZ is a direct alternative with identical electrical specifications but uses tube packaging instead of reel. Both parts share the same SOIC-16 footprint and performance metrics. Verify packaging compatibility with automated assembly equipment when substituting.
