ADM706PAN

Supervisors Overview

The ADM706PAN is a microprocessor supervisory circuit manufactured by Analog Devices Inc., designed to monitor voltage levels in electronic systems. It operates within a supply voltage range of 3.15 V to 5.5 V and features a threshold voltage of 4.4 V for under-voltage detection. The device provides an active low, push-pull output with a reset delay time of 200 ms. It includes manual reset capability and a watchdog timer function. The component is housed in an 8-pin PDIP package and supports through-hole mounting. It functions across a temperature range of -40°C to +85°C with a typical operating current of 100 µA.

Supervisors Feature Summary

• Integrates manual reset input and watchdog timer for comprehensive system supervision
• Provides active low push-pull output for direct interface with logic circuits
• Supports power-fail detection to monitor supply voltage integrity

Supervisors Applications

• Microprocessor power supply monitoring
• Battery-powered system supervision
• Industrial control system reset generation

Supervisors Procurement Notes

Verify the specific suffix PAN indicates the PDIP-8 package variant when sourcing. Confirm RoHS compliance status as it may vary by production batch. Check lead times due to potential limited availability or obsolescence notices associated with older supervisory IC families. Ensure the manual reset pin configuration matches the target schematic design requirements before procurement.

Supervisors Selection Notes

Select this component when a through-hole PDIP package is required for prototyping or legacy board designs. Compare the 4.4 V threshold against other variants like the 3.08 V option if lower voltage monitoring is needed. Consider the 100 µA quiescent current for battery life calculations. Verify that the 200 ms reset delay meets the timing requirements of the controlled microprocessor.

Supervisors Part Context

The ADM706 series belongs to Analog Devices' line of low-cost microprocessor supervisory circuits. It is part of a family that includes various threshold voltages and package options such as SOIC and TSSOP. The PAN suffix specifically denotes the plastic dual in-line package version, distinguishing it from surface-mount alternatives like the AR or TAR variants within the same functional family.

Supervisors Replacement Considerations

MAX706PCSA+T is a documented substitute offering similar supervisory functions in a surface-mount package.
