ADM6339NARJZ-RL7

Supervisors Overview

The ADM6339NARJZ-RL7 is a quad voltage microprocessor supervisory circuit manufactured by Analog Devices Inc. It monitors four independent supply voltages with fixed thresholds of 1.23 V, 3 V, and 5 V, alongside one adjustable threshold. The device features an active low, open-drain reset output with a manual reset input and a fixed 200 ms reset delay. It operates within a supply voltage range up to 5.5 V and consumes 55 uA of quiescent current. The component is housed in a SOT-23-6 package and functions reliably across an industrial temperature range from -40 C to +85 C.

Supervisors Feature Summary

• Monitors four distinct power rails simultaneously using dedicated inputs
• Provides manual reset capability via a dedicated control pin
• Delivers active low reset signals through an open-drain interface
• Integrates a fixed timing delay for stable power-up sequencing

Supervisors Applications

• Multi-rail embedded system power management
• Industrial controller board supervision
• Communication equipment voltage monitoring
• Portable electronic device power integrity checks

Supervisors Procurement Notes

Verify the exact suffix RL7 for reel packaging configuration. Confirm the NARJZ designation matches the required threshold combination of 1.23 V, 3 V, and 5 V. Check RoHS compliance status directly with the manufacturer or authorized distributors. Ensure the SOT-23-6 footprint aligns with the target PCB layout. Validate availability status as supply may be limited or subject to allocation.

Supervisors Selection Notes

Select this part when simultaneous monitoring of four specific voltage levels is required without external comparator circuits. The fixed thresholds simplify design for standard logic and analog rails. Consider the 55 uA quiescent current for battery-sensitive applications. Verify that the open-drain output type suits the downstream logic interface requirements. Ensure the operating temperature range meets the environmental conditions of the final assembly.

Supervisors Part Context

This component belongs to the ADM6339 series of quad voltage supervisors. It shares the same functional architecture and package style with variants like ADM6339PARJZ-RL7 and ADM6339LARJZ-RL7, differing primarily in the specific voltage threshold combinations programmed into the internal reference network. The series provides a compact solution for complex power systems requiring multiple supervision points.

Supervisors Replacement Considerations

ADM6339PARJZ-RL7 offers similar functionality with different threshold values including 3.3 V and 5 V options. ADM6339MARJZ-RL7 provides alternative threshold configurations for varying rail requirements. Cross-reference datasheets to ensure electrical compatibility before substitution.
