ADM706TAR-REEL

Supervisors Overview

The ADM706TAR-REEL is a microprocessor supervisory circuit manufactured by Analog Devices Inc., designed for monitoring power supplies and battery systems. It operates within a supply voltage range of 1.0 V to 5.5 V with a maximum operating voltage of 5.5 V. The device features a precision voltage monitor threshold of 4.4 V and an overvoltage threshold of 4.5 V. It provides a push-pull output type with a reset delay time of 200 ms. The quiescent current is specified at 190 uA, and the power dissipation is 470 mW. It includes a manual reset input and an independent watchdog timer with a 1.6-second timeout. The component is housed in an 8-SOIC package and supports surface mount installation.

Supervisors Feature Summary

• Integrates an independent watchdog timer with a 1.6-second timeout for system reliability
• Provides precise voltage monitoring with a 4.4 V threshold for power-fail detection
• Includes a debounced TTL/CMOS compatible manual reset input for user control

Supervisors Applications

• Microprocessor systems requiring critical power supervision
• Controllers and intelligent instruments needing reliable reset generation
• Computer systems monitoring 5 V power supplies or batteries

Supervisors Procurement Notes

Verify the specific suffix 'REEL' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status as the base part number may have varying environmental certifications depending on the manufacturing batch. Ensure the SOIC-8 package dimensions match your PCB footprint requirements before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when a dedicated watchdog timer and manual reset capability are required alongside voltage supervision. Compare the 4.4 V threshold against your system's nominal voltage to ensure proper triggering. Consider the 190 uA quiescent current if power efficiency is a primary design constraint for battery-operated applications.

Supervisors Part Context

This part belongs to the ADM706 series of microprocessor supervisory circuits from Analog Devices. It serves as a specialized integrated circuit for generating reset signals based on power supply conditions. The series is known for providing superior upgrades for legacy MAX705/MAX708 components in embedded designs.

Supervisors Replacement Considerations

Public confirmed substitute part numbers include ADM706TARZ and ADM706TARZ-REEL. Verify pin compatibility and electrical specifications before substitution.
