ADM8699ARN-REEL

Supervisors Overview

The ADM8699ARN-REEL is a microprocessor supervisory circuit manufactured by Analog Devices Inc., designed to monitor voltage levels and ensure system reliability. It operates within a supply voltage range of 2.5 V to 5.5 V and features a fixed reset threshold voltage of 4.65 V with an accuracy of 2.5%. The device provides a push-pull active-low output and includes a watchdog timer with a timeout period of 140 ms. It supports battery backup switching for seamless power transitions. The component functions reliably across an industrial temperature range from -40°C to +85°C, consuming a typical operating current of 200 µA.

Supervisors Feature Summary

• Integrated watchdog timer with manual reset input capability
• Battery backup switch functionality for uninterrupted operation during power transitions
• Push-pull active-low reset output driver
• Fixed 4.65 V threshold voltage with high precision

Supervisors Applications

• Microprocessor system supervision in embedded controllers
• Watchdog timer implementation in industrial automation equipment
• Power management monitoring in portable battery-operated devices
• Voltage supervision in telecommunications infrastructure hardware

Supervisors Procurement Notes

Verify the specific suffix 'ARN-REEL' against official Analog Devices documentation to confirm reel packaging specifications and tape-and-reel dimensions. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary. Ensure the part number matches the exact pinout and electrical characteristics required for your design before procurement.

Supervisors Selection Notes

Select this component when a fixed 4.65 V threshold is required for 3.3 V or 5 V systems. The integrated watchdog timer simplifies software-based fault recovery. Consider the SOIC-8 package size for space-constrained PCB layouts. Verify that the active-low output polarity aligns with the target microprocessor reset input requirements.

Supervisors Part Context

The ADM8699 belongs to the ADM869x series of improved microprocessor supervisors, offering enhanced performance over earlier generations like the ADM699. It combines voltage monitoring with watchdog functionality in a compact surface-mount package. This series is widely used in applications requiring robust power management and system reset capabilities without external components.

Supervisors Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include the ADM709LARZ and ADM8698ARN. Verify compatibility regarding reset delay times, watchdog functionality, and package dimensions before substitution.
