ADM706TAR

Supervisors Overview

The ADM706TAR is a microprocessor supervisory circuit designed for monitoring 5 V power supplies and batteries. It features a precision voltage monitor with a threshold of 4.40 V and an independent watchdog timer with a 1.60-second timeout. The device provides a debounced manual reset input and operates with a quiescent current of 190 μA. It supports a supply voltage range up to 5.5 V, ensures valid RESET signals down to 1 V, and includes a 200 ms reset pulse width. The component is housed in an 8-SOIC package.

Supervisors Feature Summary

• Integrates an independent watchdog timer with a fixed 1.60-second timeout interval for system activity monitoring
• Provides a debounced manual reset input compatible with TTL/CMOS logic levels
• Guarantees valid RESET output signals even when the supply voltage drops as low as 1 V

Supervisors Applications

• Microprocessor systems requiring critical supply monitoring
• Computers and controllers needing battery backup supervision
• Intelligent instruments demanding reliable power-fail warnings

Supervisors Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout compatibility and electrical tolerances. Confirm RoHS compliance status and manufacturing origin details directly from the datasheet before integration into production designs.

Supervisors Selection Notes

Select this component when a fixed 4.40 V threshold and integrated watchdog functionality are required. Compare the 190 μA quiescent current against system power budgets. Ensure the 8-SOIC package dimensions fit the target PCB layout constraints.

Supervisors Part Context

This part belongs to the ADM705/ADM706/ADM707/ADM708 family of supervisory circuits. These devices serve as superior upgrades for legacy MAX705 to MAX708 components, offering similar functionality with potentially improved specifications or availability within the Analog Devices portfolio.

Supervisors Replacement Considerations

Public confirmed substitute part numbers include ADM706TARZ and ADM706TAR-REEL.
