ADM8690ARN-REEL

Supervisors Overview

The ADM8690ARN-REEL is a microprocessor supervisory circuit manufactured by Analog Devices Inc. in an SOIC-8 surface-mount package. It provides comprehensive power management functions including reset assertion, watchdog timer, and battery backup switching. The device features a fixed reset threshold voltage of 4.65 V with a reset delay time of 50 ms. It operates within a supply voltage range up to 5.5 V and maintains a low operating current of 200 uA. The component supports active low push-pull outputs and includes overvoltage detection at 4.73 V.

Supervisors Feature Summary

• Integrates complete single-chip solutions for power supply monitoring and battery control functions in microprocessor systems
• Provides automatic battery backup power switching with high current drive capabilities
• Includes a configurable watchdog timer for system stability monitoring

Supervisors Applications

• Microprocessor systems requiring reliable power supervision
• Computer hardware and controller boards
• Intelligent instruments needing voltage monitoring
• Automotive electronic systems

Supervisors Procurement Notes

Verify the specific suffix configuration against official Analog Devices documentation to ensure compatibility with required packaging and thermal specifications. Confirm that the REEL designation matches the intended manufacturing process requirements. Cross-reference the exact part number with the manufacturer's current product status to avoid obsolescence risks associated with discontinued lines.

Supervisors Selection Notes

Select this component when a dedicated supervisory circuit with integrated watchdog and backup switching is required. The fixed 4.65 V threshold suits standard 5 V logic systems. Consider the SOIC-8 package for space-constrained surface-mount designs. Evaluate the low standby current for power-sensitive applications compared to older generations like the ADM690.

Supervisors Part Context

This part belongs to the ADM8690 family of microprocessor supervisory circuits, designed as an upgrade to earlier models such as the ADM690. The family offers various configurations to satisfy diverse microprocessor system requirements. The ADM8690 specifically focuses on providing precision voltage monitoring and reset generation in a compact form factor suitable for modern electronics.

Supervisors Replacement Considerations

Public confirmed substitute part numbers include ADM8690ANZ and ADM8690ARN. Verify pinout compatibility and electrical parameter alignment before substitution. Check for any differences in package tolerance or temperature range specifications between the original and replacement parts.
