ADM706RAN

Supervisors Overview

The ADM706RAN is a microprocessor supervisory circuit manufactured by Analog Devices Inc., designed for monitoring power supplies and battery levels. It features a precision voltage monitor with a threshold of 4.4 V and an independent watchdog timer with a 1.6-second timeout. The device provides a debounced manual reset input and operates within a supply voltage range up to 5.5 V. It delivers a push-pull active low reset output with a 280 ms reset pulse width, ensuring valid resets down to 1 V. The component consumes 250 uA of quiescent current and functions reliably across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates an independent watchdog timer with a fixed timeout period for system reliability
• Provides a debounced manual reset input compatible with TTL/CMOS logic levels
• Delivers a push-pull active low reset output for direct microprocessor interfacing
• Ensures valid reset signals at supply voltages as low as 1 V

Supervisors Applications

• Microprocessor systems requiring critical supply monitoring
• Controllers and intelligent instruments needing power-fail detection
• Computers and embedded devices utilizing battery backup scenarios

Supervisors Procurement Notes

Verify the specific suffix against official documentation to confirm package type and temperature grade. Confirm RoHS compliance status as manufacturing revisions may vary. Check current availability through authorized distributors, as lead times and stock levels fluctuate. Ensure the ordering part number matches the required pinout and electrical specifications for your design.

Supervisors Selection Notes

Select this component when a fixed 4.4 V threshold and integrated watchdog are required. Compare quiescent current and reset delay against alternatives if power efficiency or speed is critical. Verify that the SOIC-8 package fits the PCB layout constraints. Consider the manual reset feature requirements versus programmable options in newer generations.

Supervisors Part Context

The ADM706 belongs to the ADM705/ADM706/ADM707/ADM708 family of low-cost supervisory circuits. These devices serve as upgrades for legacy MAX705-MAX708 parts. The 'R' suffix typically denotes an SOIC-8 surface-mount package variant within the series, distinguishing it from DIP or other package options available in the same product line.

Supervisors Replacement Considerations

The ADM706AR is a reel-packaged version of the same functional device. Cross-reference with ADM706SANZ for through-hole equivalents. Verify pin compatibility before substituting with other ADM706 variants.
