ADM699AR

Supervisors Overview

The ADM699AR is a CMOS supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single voltage inputs within a range of 3 V to 5.5 V. It features a push-pull output and integrates a watchdog timer without manual reset or battery backup switching capabilities. The device operates with a supply current of 1.95 mA and provides a reset delay time of 200 ms, alongside an overvoltage threshold of 4.73 V. It is housed in a SOIC-16 package and supports surface-mount installation across an operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Provides push-pull output configuration for direct interface compatibility
• Operates within a wide supply voltage range up to 5.5 V

Supervisors Applications

• Embedded systems requiring voltage supervision
• Microcontroller power management circuits
• Industrial control units needing watchdog functionality

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as the specific variant may not meet current standards. Validate package integrity and pin alignment against original specifications before integration into production lines.

Supervisors Selection Notes

Select this component when a single-input supervisor with integrated watchdog is required. Ensure the 200 ms reset delay aligns with system startup timing constraints. Verify that the SOIC-16 footprint matches the PCB design and that the operating temperature range suits the deployment environment.

Supervisors Part Context

Part of the ADM699 series of voltage supervisors. Shares core supervisory functions with variants like ADM699ARZ but differs in packaging and regulatory compliance attributes. Designed for general-purpose power management in digital logic applications.
