ADM8699ARW

Supervisors Overview

The ADM8699ARW is a supervisory circuit from Analog Devices, packaged in a 16-SOIC format. 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 active low, push-pull output and includes a watchdog timer for microprocessor activity monitoring. Reset delay time is specified at 200 ms. Operating supply voltage maximum is 5.5 V, with a typical operating current of 200 uA. Accuracy is rated at 2.5%. Power dissipation is 600 mW. The component operates within a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrated watchdog timer input for monitoring microprocessor activity
• Power supply monitoring with dedicated reset output
• Push-pull active low output driver

Supervisors Applications

• Microprocessor system power supervision
• Watchdog timing circuits
• Battery backup switching systems

Supervisors Procurement Notes

Verify the specific suffix ARW indicates the 16-SOIC package configuration. Confirm RoHS compliance status through official documentation. Check for obsolescence or limited availability as distribution status varies. Ensure the active low output polarity matches system requirements. Validate thermal performance within the specified operating temperature range.

Supervisors Selection Notes

Select this component when microprocessor activity monitoring via a watchdog timer is required alongside standard voltage supervision. The 16-SOIC package suits surface mount applications needing multiple pins for control signals. Verify that the 4.65 V threshold aligns with the target supply rail. Consider the 200 ms reset delay for system startup stability. Compare against the ADM8698 if watchdog functionality is not needed.

Supervisors Part Context

The ADM8699 belongs to the ADM869x series of supervisory circuits designed for embedded systems. It shares the core monitoring architecture with the ADM8698 but adds a watchdog input pin. This series targets industrial and commercial applications requiring reliable power management. The 16-SOIC package provides ample pin count for additional control features compared to smaller packages.

Supervisors Replacement Considerations

Public confirmed substitutes include ADM709LARZ, ADM8699ARNZ, MAX705ESA+, and MAX709LESA+. Verify pinout compatibility and package dimensions before substitution. Ensure the replacement supports the required watchdog functionality if present in the original design.
