ADM1813-10ARTZ-RL7

Supervisors Overview

The ADM1813-10ARTZ-RL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed to monitor system power integrity. It operates within a supply voltage range of 2.5 V to 5.5 V and features a fixed reset threshold voltage of 4.49 V. The device provides a push-pull output and includes a manual reset input for controlled system recovery. It incorporates a fixed 250 ms reset delay time to ensure stable operation during power transitions. The component supports single-input monitoring and functions without a watchdog timer or battery backup switch. It is housed in an SC-70-3 surface-mount package and maintains low quiescent current consumption of 16 uA across the industrial temperature range of -40 C to +105 C.

Supervisors Feature Summary

• Includes a manual reset input for controlled system recovery
• Features a fixed 250 ms reset delay time for stability
• Provides a push-pull output configuration
• Operates with low quiescent current consumption

Supervisors Applications

• Portable equipment requiring reliable power supervision
• Battery-powered systems needing voltage monitoring
• Microprocessor reset circuits
• Smart cards and smart card readers

Supervisors Procurement Notes

Verify the specific suffix ARTZ against official documentation to confirm the package type and tape-and-reel configuration, as suffixes define physical attributes rather than electrical function. Confirm availability status through authorized channels, as this part may be discontinued or subject to limited supply constraints. Ensure compatibility with existing PCB footprints for the SC-70-3 package before procurement.

Supervisors Selection Notes

Select this component when a fixed 4.49 V threshold is required for system monitoring. The inclusion of a manual reset input distinguishes it from variants lacking this feature. Verify that the SC-70-3 package dimensions fit the design constraints. Consider the 250 ms delay duration to ensure it aligns with the target system's startup timing requirements.

Supervisors Part Context

This part belongs to the ADM1813 series of supervisory circuits from Analog Devices. The series offers various threshold voltages and packaging options. The ADM1813-10ARTZ-RL7 specifically denotes the 4.49 V threshold variant in the SC-70-3 package with reel packaging. It serves as a dedicated solution for maintaining system reliability in compact electronic designs.

Supervisors Replacement Considerations

Check for ADM1813 variants with different threshold voltages if the 4.49 V level is unsuitable. Verify pinout compatibility with other ADM1813 family members. Consult official substitution lists for any updated versions or alternative packages within the same product line.
