ADM809MART-REEL

Supervisors Overview

The ADM809MART-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single-input power rails. It operates within a supply voltage range of 1 V to 5.5 V and features a push-pull output configuration. The device supports surface-mount installation in an SOT-23-3 package and functions reliably across an extended temperature range from -40°C to +125°C. It consumes 60 µA of operating current and lacks manual reset, watchdog timer, or battery backup switching capabilities.

Supervisors Feature Summary

• Provides voltage supervision with a push-pull output interface for direct logic integration
• Operates over a wide supply voltage range from 1 V to 5.5 V
• Designed for high-temperature environments with operation up to +125°C

Supervisors Applications

• Microprocessor system reset generation
• Portable equipment power management
• Industrial control voltage monitoring

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to discontinued status. Confirm RoHS compliance requirements as the specific variant may not meet current environmental standards. Validate package integrity and pin alignment against SOT-23-3 specifications before implementation. Ensure design compatibility with existing thermal and electrical constraints.

Supervisors Selection Notes

Select this component when a simple, low-current supervisor is required for voltages up to 5.5 V. The absence of a manual reset input simplifies board layout but limits user intervention. Consider the fixed threshold characteristics and ensure they align with the target rail's nominal voltage. The SOT-23-3 package offers space efficiency for compact designs.

Supervisors Part Context

This part belongs to the ADM809 series of supervisory circuits from Analog Devices. It shares functional similarities with other members like the ADM809MARTZ-REEL7, though differences exist in regulatory compliance and specific threshold documentation. The series focuses on providing reliable reset signals for digital systems without complex configuration options.

Supervisors Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternatives based on matching voltage ranges, package types, and output configurations.
