ADM8695ARW

Supervisors Overview

The ADM8695ARW is a microprocessor supervisory circuit from Analog Devices, designed for power supply monitoring and battery control. It features a 4.65 V threshold voltage with 2.5% accuracy and a 200 ms reset delay. The device operates within a 1 V to 5.5 V range, consuming only 0.7 mW. It includes a watchdog timer, backup battery switchover, and CMOS RAM write protection. The output is active low push-pull, capable of 100 mA drive current. It functions in the -40°C to +85°C temperature range.

Supervisors Feature Summary

• Integrated watchdog timer with selectable timeout periods
• Automatic battery backup power switching mechanism
• Power failure warning capability with fast gating
• CMOS RAM write protection function

Supervisors Applications

• Microprocessor system power monitoring
• Battery-powered instrumentation backup control
• Industrial controller voltage supervision
• Automotive electronic system protection

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm package integrity and pin alignment against SOIC-16 specifications. Validate datasheet revision compatibility with existing design requirements. Ensure thermal management aligns with specified power dissipation limits during operation.

Supervisors Selection Notes

Select this component when precise voltage monitoring and integrated battery management are required. Consider the fixed 4.65 V threshold and 200 ms delay for system timing constraints. Evaluate the SOIC-16 package suitability for PCB layout. Verify that the active low output drives the target microprocessor reset line correctly.

Supervisors Part Context

Part of the ADM8690–ADM8695 family of supervisory circuits. Designed as an upgrade for older ADM690/ADM695 series components. Offers enhanced precision and lower power consumption compared to predecessors. Provides a complete single-chip solution for complex microprocessor system supervision tasks.

Supervisors Replacement Considerations

Check for ADM8690ANZ or ADM8695ARNZ equivalents if available. Verify functional compatibility regarding threshold voltages and reset delays. Assess package pinout correspondence for direct replacement scenarios.
