ADM9690ARN-REEL

Supervisors Overview

The ADM9690ARN-REEL is a single-channel supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range up to 5.5 V and features an open-collector output type. The device includes a watchdog timer and battery backup switch functionality, with a reset delay time of 200 ms. It is designed for surface mount installation in an 8-pin SOIC package. The component monitors one input voltage and provides power failure detection capabilities. Operating temperatures range from -40°C to +85°C, ensuring reliability in industrial environments.

Supervisors Feature Summary

• Integrated watchdog timer for system monitoring
• Battery backup switch capability
• Power failure detection feature
• Single voltage input monitoring

Supervisors Applications

• Industrial control systems
• Embedded processor supervision
• Communication equipment power management

Supervisors Procurement Notes

Verify the specific suffix REEL indicates tape-and-reel packaging when ordering. Confirm the manufacturer part number matches exactly as ADM9690ARN-REEL to ensure correct pinout and electrical characteristics. Check RoHS compliance status through official distributor channels prior to procurement. Ensure storage conditions meet humidity sensitivity requirements specified in the datasheet.

Supervisors Selection Notes

Select this component when a single-supervisor IC with integrated watchdog functionality is required. Compare against similar parts like ADM690AARNZ if manual reset or different threshold voltages are needed. Consider the open-collector output compatibility with downstream logic levels. Evaluate thermal performance within the specified operating temperature range for the target application environment.

Supervisors Part Context

This part belongs to the ADM9690 series of supervisory circuits from Analog Devices. It is distinct from the AD9690 ADC series which shares a similar numerical prefix but serves a completely different function. The ADM9690 is specifically designed for power management and system reset applications rather than data conversion.

Supervisors Replacement Considerations

Direct replacements may include ADM9690ARNZ (tube packaging) or ADM9690ARN-REEL variants. Verify pin compatibility and electrical specifications before substituting. Cross-reference with ADM690AARNZ only if functional differences such as manual reset are acceptable.
