ADM698ARZ-REEL

Supervisors Overview

The ADM698ARZ-REEL is a microprocessor supervisory circuit manufactured by Analog Devices Inc., housed in a 16-SOIC package. It monitors a single voltage input with a threshold of 4.65 V and an overvoltage threshold of 4.73 V. The device features an open-drain output, a watchdog timer, and a battery backup switch. Reset delay is 200 ms, with a maximum supply voltage of 5.5 V. Operating current is 1.95 mA, power dissipation is 600 mW, and the temperature range is -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Includes a battery backup switch function for power continuity
• Provides open-drain reset output capability

Supervisors Applications

• Microprocessor system supervision
• Power failure detection circuits
• Battery backup switching applications

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to potential limited availability. Confirm RoHS compliance status and check for specific reel packaging requirements. Ensure the supplier provides valid traceability documentation. Validate that the received part matches the ADM698ARZ-REEL designation exactly. Review datasheet specifications against application needs before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when a single-channel supervisory circuit with integrated watchdog functionality is required. Consider the 4.65 V threshold and 200 ms reset delay for timing compatibility. Evaluate the open-drain output type against load requirements. Verify that the 1.95 mA operating current fits within system power budgets. Ensure the SOIC-16 package aligns with PCB layout constraints.

Supervisors Part Context

This part belongs to the ADM69x series of microprocessor supervisory circuits from Analog Devices. It shares functional similarities with the ADM691 and ADM699 but offers specific threshold and feature combinations. The series is designed for reliable system monitoring in industrial and commercial environments. Check related parts like the ADM696 or ADM8696 for alternative threshold options.
