ADM706RARZ-REEL

Supervisors Overview

The ADM706RARZ-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for monitoring power supply integrity in electronic systems. It operates within a supply voltage range of 1.0 V to 5.5 V and features a fixed threshold voltage of 4.4 V for under-voltage detection. The device provides a push-pull output and includes a manual reset input alongside an integrated watchdog timer with a 1.6-second timeout period. It delivers a reset pulse width of 200 ms and consumes 190 uA of operating current. The component is housed in an SOIC-8 package and supports operation across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer with a 1.6-second timeout for system reliability
• Includes a debounced manual reset input for user-initiated control
• Provides power-fail detection capability via a dedicated output pin

Supervisors Applications

• Microprocessor system power supervision
• Computer controller reset generation
• Smart instrument voltage monitoring
• Critical microprocessor power management

Supervisors Procurement Notes

Verify the specific suffix REEL against official Analog Devices documentation to confirm reel packaging specifications and quantity per unit. Ensure compatibility with existing PCB footprints for the SOIC-8 package. Cross-reference the 4.4 V threshold requirement with system design parameters to confirm adequate margin for the target application voltage.

Supervisors Selection Notes

Select this component when a fixed 4.4 V threshold is required for single-input voltage monitoring. The inclusion of both a manual reset input and a watchdog timer makes it suitable for complex systems requiring multiple reset mechanisms. Consider the 190 uA quiescent current for battery-powered designs, ensuring it aligns with overall power budget constraints compared to lower-current alternatives.

Supervisors Part Context

This part belongs to the ADM706 series of microprocessor supervisory circuits from Analog Devices. The series offers various threshold voltages and feature combinations, including options with or without watchdog timers and manual resets. The RARZ variant specifically denotes the 4.4 V threshold version with integrated watchdog and manual reset capabilities in a standard industrial temperature grade package.
