ADM809MARTZ-REEL

Supervisors Overview

The ADM809MARTZ-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single power supply inputs. It operates within a supply voltage range of 1 V to 5.5 V and features a threshold voltage of 4.38 V with an accuracy of 1.5%. The device provides a push-pull output and includes a reset delay time of 240 ms. It consumes 60 uA of operating current and functions across a temperature range of -40 C to +125 C. Packaged in SOT-23-3, it lacks manual reset, watchdog timer, or battery backup switch capabilities.

Supervisors Feature Summary

• Monitors a single input voltage with high precision
• Provides active low reset signal via push-pull output
• Operates efficiently with low quiescent current consumption

Supervisors Applications

• Microprocessor system reset circuits
• Portable instrumentation power supervision
• Battery-powered device voltage monitoring

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to limited availability. Confirm RoHS compliance status as specified in official documentation. Check regional distribution restrictions before ordering. Ensure package type matches design requirements. Validate thermal performance against application constraints.

Supervisors Selection Notes

Select this part when precise voltage supervision is required for single-rail systems. Consider the 4.38 V threshold for standard logic levels. Evaluate the 240 ms delay against system startup timing needs. Assess the SOT-23-3 package for space-constrained designs. Compare current consumption against battery life requirements.

Supervisors Part Context

Part of the ADM809 series from Analog Devices, focusing on voltage supervision. Shares common family traits like low current draw but differs in specific threshold voltages and packaging options. Designed for reliable operation in harsh environments with wide temperature tolerance.

Supervisors Replacement Considerations

Check for ADM809 variants with similar thresholds. Verify pin compatibility for direct substitution. Confirm electrical specifications match original design requirements.
