ADM810ZART-REEL

Supervisors Overview

The ADM810ZART-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc., designed as a microprocessor supervisor in an SC-70 package. It features a push-pull output and monitors a single input with a threshold voltage of 2.63V. The device operates within a supply voltage range up to 5.5V and includes an overvoltage threshold of 2.66V. It provides a reset delay time of 140ms minimum and maintains accuracy within 1.5%. The component supports surface mount installation and functions across a temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Provides simple reset generation for power supply monitoring without manual reset or watchdog timer functionality
• Features push-pull/totem pole output configuration for direct interface with digital logic
• Operates with low supply current consumption suitable for battery-powered applications

Supervisors Applications

• Microprocessor system power supervision
• Portable electronic device voltage monitoring
• Industrial control board power integrity verification

Supervisors Procurement Notes

Verify the exact suffix and package type against official datasheets, as variations exist within the ADM810 family. Confirm availability status as some variants are marked obsolete or have limited supply. Ensure the specific threshold voltage matches design requirements before procurement.

Supervisors Selection Notes

Select this component when a compact SC-70 package is required for space-constrained designs. Choose based on the specific 2.63V threshold requirement for the monitored rail. Consider the operating temperature range and output drive capability relative to the load connected to the reset pin.

Supervisors Part Context

This part belongs to the ADM810 series of voltage supervisors from Analog Devices. The series offers various threshold voltages and packages to accommodate different system requirements. The ADM810ZART variant specifically targets applications needing a lower voltage threshold in a small outline transistor package.

Supervisors Replacement Considerations

Check for ADM810LART or ADM810TART if different thresholds are acceptable. Verify pin compatibility with SOT-23-3 alternatives if package changes are permissible.
