ADM802LARN-REEL

Supervisors Overview

The ADM802LARN-REEL is a microprocessor supervisory circuit manufactured by Analog Devices Inc., housed in an 8-SOIC package. It features a precise voltage threshold of 4.65 V and includes an integrated watchdog timer for system reliability. The device operates with a maximum supply voltage of 5.5 V and maintains low power consumption, drawing only 100 uA during operation. It provides push-pull output capabilities and functions within a temperature range of -40°C to +85°C, ensuring stable performance in industrial environments.

Supervisors Feature Summary

• Integrates a watchdog timer for automated system recovery from software faults
• Provides precise voltage monitoring with a fixed 4.65 V threshold
• Features push-pull output stage for robust signal driving capability

Supervisors Applications

• Microprocessor system supervision
• Industrial control unit monitoring
• Embedded system reset generation

Supervisors Procurement Notes

Verify the specific suffix REEL indicates reel packaging when sourcing. Confirm the manufacturer is Analog Devices Inc. as specified. Check current availability status as distribution may vary. Ensure the 8-SOIC package matches your PCB footprint requirements. Validate RoHS compliance documentation if required for your manufacturing process.

Supervisors Selection Notes

Select this component when a dedicated supervisor with watchdog functionality is required. The 4.65 V threshold suits standard 5 V logic systems. Consider the SOIC-8 package for surface mount assembly compatibility. Evaluate the 100 uA quiescent current against system power budgets. Ensure the operating temperature range meets environmental specifications.

Supervisors Part Context

This part belongs to the ADM802 series of supervisory circuits from Analog Devices. It is designed specifically for monitoring voltage levels in digital systems. The series offers various threshold options and package types. The ADM802 variant focuses on providing essential reset and watchdog features in a compact form factor suitable for space-constrained designs.

Supervisors Replacement Considerations

Check for ADM802LARN without the reel suffix for tube packaging equivalents. Verify functional compatibility with other ADM802 family members. Ensure pinout and electrical characteristics match exactly before substitution.
