ADM8697ARWZ

Supervisors Overview

The ADM8697ARWZ is a supervisory circuit from Analog Devices, packaged in a 16-SOIC. It features a 1.3 V threshold voltage and monitors one input. The device provides active high and active low outputs with a 50 ms reset delay. It includes a watchdog timer and battery backup switch functionality. Operating supply current is 200 uA, with power dissipation of 600 mW. Accuracy is specified at 2.5%. The component operates within a temperature range of -40°C to +85°C and supports a maximum supply voltage of 5.5 V.

Supervisors Feature Summary

• Integrated watchdog timer for system fault detection
• Battery backup switching capability for data retention
• Dual output polarity options (active high/low)
• Power fail detection monitoring

Supervisors Applications

• Portable equipment requiring battery management
• Microprocessor systems needing power supervision
• Industrial control units with watchdog requirements

Supervisors Procurement Notes

Verify the specific suffix 'ARWZ' against the official datasheet to confirm package type and temperature grade. Confirm end-of-life status as some sources indicate obsolescence. Ensure compatibility with existing PCB footprint and voltage levels before procurement.

Supervisors Selection Notes

Select this component when a 1.3 V threshold is required for single-input monitoring. Consider the 16-SOIC package constraints and 200 uA quiescent current. Verify if the integrated watchdog and battery backup features meet system design needs without external components.

Supervisors Part Context

Part of the ADM8696/ADM8697 series, offering improved performance over legacy ADM696/ADM697 ICs. Designed for reliable power supervision in compact surface-mount applications. Manufactured by Analog Devices Inc. using specialized processes for accuracy and stability.

Supervisors Replacement Considerations

Check for ADM8696 variants if different thresholds are needed. Verify availability of direct pin-compatible substitutes due to potential end-of-life status. Consult official documentation for updated lifecycle information.
