ADM6339AARJZ-RL7

Supervisors Overview

The ADM6339AARJZ-RL7 is a quad voltage monitor supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range up to 5.5 V and features four independent monitoring inputs with fixed threshold voltages of 1.23 V, 2.19 V, 2.93 V, and 4.38 V. The device provides an active low, open-drain output with a manual reset input and a fixed reset delay time of 200 ms. It consumes 55 uA of operating current and lacks watchdog or battery backup functions. The component is housed in a SOT-23-6 package and supports surface mount installation across an industrial temperature range from -40 C to +85 C.

Supervisors Feature Summary

• Monitors four distinct power rails simultaneously using fixed internal thresholds
• Provides active low open-drain status output for system integration
• Includes manual reset capability for controlled system recovery

Supervisors Applications

• Multi-rail power supply supervision in embedded systems
• Voltage monitoring for portable electronic devices
• Industrial control board power integrity verification

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to limited availability status. Confirm RoHS compliance details prior to integration. Check datasheet specifications against current design requirements as manufacturing status may indicate end-of-life conditions. Ensure packaging format matches assembly line capabilities.

Supervisors Selection Notes

Select this component when simultaneous monitoring of four specific voltage levels is required without complex configuration. The fixed thresholds eliminate external resistor networks. Consider the SOT-23-6 footprint constraints and manual reset requirement during schematic design. Verify that the 200 ms delay aligns with system startup timing needs.

Supervisors Part Context

This part belongs to the ADM6339 series of supervisory circuits designed for compact multi-voltage monitoring applications. It shares functional similarities with other variants in the family but differs in specific threshold configurations. The A suffix indicates specific factory-set voltage levels compared to adjustable alternatives.

Supervisors Replacement Considerations

ADM6339QARJZ-RL7 and ADM6339LARJZ-RL7 are related quad voltage monitors within the same series. Verify threshold voltage compatibility before substitution as these variants utilize different fixed or adjustable settings.
