ADM706PAR-REEL

Supervisors Overview

The ADM706PAR-REEL is a microprocessor supervisory circuit manufactured by Analog Devices Inc. It monitors supply voltages and includes an independent watchdog timer with a 1.6-second timeout. The device features a debounced manual reset input and provides a push-pull active low reset output. It operates within a supply voltage range of 3 V to 5.5 V, with a typical threshold of 4.4 V. The quiescent current is 250 µA, and the reset pulse width is 280 ms. It functions from -40°C to +85°C in an 8-pin SOIC package.

Supervisors Feature Summary

• Integrated independent watchdog timer for monitoring processor activity
• Debounced manual reset input for system control
• Active low push-pull reset output driver
• Guaranteed valid reset signal down to 1 V supply

Supervisors Applications

• Microprocessor systems
• Computers and controllers
• Intelligent instruments
• Critical microprocessor supply monitoring

Supervisors Procurement Notes

Verify the specific suffix against official documentation, as variations exist within the ADM706 family. Confirm RoHS compliance status and manufacturing origin via the datasheet. Check availability through authorized distributors, as stock levels fluctuate. Ensure the package type matches the design requirements before ordering.

Supervisors Selection Notes

Select this component when a dedicated watchdog timer and manual reset are required alongside voltage supervision. Compare the 4.4 V threshold against other variants like the ADM705 or ADM707 if different voltage levels are needed. Consider the 250 µA quiescent current for power-sensitive designs. Verify that the 8-pin SOIC package fits the PCB layout constraints.

Supervisors Part Context

This part belongs to the ADM705/ADM706/ADM707/ADM708 series of low-cost microprocessor supervisory circuits. These devices are designed to monitor 5 V power supplies and batteries. The ADM706 variant specifically combines voltage monitoring with an independent watchdog timer and manual reset functionality in a single integrated circuit.
