ADM692AARNZ-REEL

Supervisors Overview

The ADM692AARNZ-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 reset timeout delay of 200 ms. It integrates a watchdog timer, power-fail warning, and battery backup switchover functionality. The component is housed in an SOIC-8 surface-mount package and supports a maximum output current of 250 mA.

Supervisors Feature Summary

• Integrates battery backup switchover for seamless transition between primary and secondary power sources
• Includes a built-in watchdog timer to detect software malfunctions and system hangs
• Provides power-fail warning signals to alert the processor before voltage drops below safe operating levels

Supervisors Applications

• Microprocessor system supervision in embedded controllers
• Battery-powered devices requiring automatic switchover logic
• Industrial control systems needing watchdog protection

Supervisors Procurement Notes

Verify the specific suffix REEL against official Analog Devices documentation to confirm tape-and-reel packaging specifications. Confirm RoHS compliance status as indicated in the latest datasheet revision. Ensure the part number matches the exact threshold voltage requirements for your design, as variations exist within the ADM692 family.

Supervisors Selection Notes

Select this component when a fixed 4.4 V threshold is required for 5 V CMOS logic systems. Consider the 250 mA output drive capability if direct interfacing with high-load inputs is necessary without external buffering. Evaluate the need for integrated battery switchover versus external diode OR-ing solutions based on board space and efficiency constraints.

Supervisors Part Context

This part belongs to the ADM692A series of supervisory circuits designed for 5 V applications. It shares functional similarities with the MAX692 but offers specific pinout and feature configurations unique to the Analog Devices portfolio. The REEL suffix indicates it is supplied in continuous tape packaging suitable for automated assembly processes.

Supervisors Replacement Considerations

The MAX692AEPA+ is a documented equivalent from the Maxim Integrated line. Verify pin compatibility and electrical parameter alignment before substitution.
