ADM6339IARJZ-RL7

Supervisors Overview

The ADM6339IARJZ-RL7 is a quad voltage microprocessor supervisory circuit manufactured by Analog Devices Inc. It monitors four independent supply rails using fixed threshold voltages of 1.23 V, 2.19 V, 2.93 V, and 4.38 V. The device features an active-low open-drain reset output with a standard 200 ms timeout delay. It operates within a supply voltage range up to 5.5 V and consumes 55 uA of quiescent current. The component supports manual reset functionality and functions reliably across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Simultaneous monitoring of four distinct power supply inputs
• Manual reset input capability for system control
• Active-low open-drain reset signal generation

Supervisors Applications

• Multi-rail embedded system power management
• Industrial controller voltage supervision
• Communication equipment power integrity monitoring

Supervisors Procurement Notes

Verify the specific suffix 'I' indicates the industrial temperature grade (-40°C to +85°C) as defined in the official datasheet. Confirm package compatibility with SOT-23-6 footprints during integration. Cross-reference the exact part number against manufacturer documentation to ensure correct threshold voltage selection for the target application rails.

Supervisors Selection Notes

Select this component when simultaneous supervision of four separate voltage lines is required without external comparator circuits. The fixed thresholds simplify design compared to adjustable variants. Ensure the 55 uA operating current aligns with system power budgets. Verify that the open-drain output configuration matches the downstream logic requirements.

Supervisors Part Context

This part belongs to the ADM6339 family of quad voltage supervisors. It provides integrated monitoring for complex systems requiring multiple power domains. The SOT-23-6 package allows for compact board layouts while maintaining reliable performance in industrial environments.

Supervisors Replacement Considerations

Check ADM6339BARJZ-RL7 or ADM6339CARJZ-RL7 for alternative threshold configurations within the same series. Verify pinout compatibility before substitution.
