ADM812MART-REEL

Supervisors Overview

The ADM812MART-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc., designed to monitor a single power supply input. It operates within a maximum supply voltage of 5.5 V and features an active high output type with manual reset capability. The device provides a reset delay time of 560 ms and maintains an accuracy of 1.5%. It functions at a working supply current of 15 uA, with a power dissipation rating of 200 mW. The component supports an overvoltage threshold of 4.72 V and operates across a temperature range from -40 C to +85 C.

Supervisors Feature Summary

• Provides manual reset functionality for controlled system recovery
• Features active high output signaling for supervisor status
• Includes overvoltage detection capabilities alongside standard supervision

Supervisors Applications

• Microprocessor power supply monitoring
• Battery-powered system voltage supervision
• Embedded controller reset generation

Supervisors Procurement Notes

Verify the specific suffix and package configuration against the official datasheet to ensure compatibility with your design requirements. Confirm availability status through authorized distributors as supply conditions may vary. Check RoHS compliance details if required for your manufacturing standards. Ensure the manual reset pin is correctly integrated into your schematic.

Supervisors Selection Notes

Select this component when an active high output signal is required for the supervisory function. The manual reset feature allows for external control over the reset state, which is useful for specific initialization sequences. Consider the 15 uA quiescent current for low-power applications. Verify that the 5.5 V maximum operating voltage aligns with your system's power rail specifications.

Supervisors Part Context

This part belongs to the ADM812 series of voltage supervisors from Analog Devices. It is distinct from other series like ADM809 or ADM810 due to its specific output polarity and reset characteristics. The MART suffix indicates a specific package and tape/reel configuration suitable for surface mount assembly processes.

Supervisors Replacement Considerations

Check for direct pin-to-pin replacements within the ADM812 family with different thresholds. Verify functional equivalence if substituting with similar supervisors from other manufacturers, ensuring output polarity and reset timing match.
