ADM691AARN-REEL7

Supervisors Overview

The ADM691AARN-REEL7 is a microprocessor supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range up to 5.5 V and features a threshold voltage of 4.65 V with an overvoltage threshold of 4.75 V. The device monitors one input and provides an open-drain output type. It includes a watchdog timer, battery backup switching, and chip enable functionality, but lacks manual reset capability. The reset delay time is specified at 200 ms. Operating current is 100 uA, with maximum power dissipation of 700 mW. It functions between -40 C and +85 C and is housed in an SOIC-16 package.

Supervisors Feature Summary

• Integrates watchdog timer and battery backup switching for system reliability
• Provides open-drain output with chip enable control
• Monitors single voltage input with defined threshold levels

Supervisors Applications

• Microprocessor system supervision
• Voltage monitoring in CMOS process applications
• Power failure detection circuits

Supervisors Procurement Notes

Verify component authenticity through official Analog Devices channels or authorized distributors. Confirm the specific suffix REEL7 matches required packaging specifications. Check current lifecycle status as data indicates potential obsolescence. Ensure environmental compliance documentation aligns with project requirements. Validate pinout compatibility during integration planning.

Supervisors Selection Notes

Select this component when a single-input supervisory circuit with integrated watchdog and battery backup is required. Consider the 4.65 V threshold and 5.5 V maximum supply limits against target system voltages. Evaluate the 100 uA operating current against power constraints. Verify that the SOIC-16 package fits the design footprint. Confirm that the absence of manual reset meets system reset strategy needs.
