ADM6339JARJZ-RL7

Supervisors Overview

The ADM6339JARJZ-RL7 is a quad voltage microprocessor supervisory circuit manufactured by Analog Devices Inc. It monitors four independent supply rails using internally pretrimmed undervoltage thresholds of 5.0 V, 3.3 V, 2.5 V, and 1.8 V. The device features an active low open-drain reset output with a fixed 200 ms reset delay time. 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 lacks a watchdog timer or battery backup switch. It is housed in a compact SOT-23-6 surface-mount package and functions reliably across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Monitors four distinct power supply rails with factory-trimmed thresholds for common logic levels
• Provides a synchronized active low open-drain reset signal with a guaranteed 200 ms delay
• Supports manual system reset via dedicated input pin without requiring external components

Supervisors Applications

• Multi-rail embedded system power supervision
• Microprocessor board voltage monitoring
• Industrial control unit power integrity verification
• Communication equipment power rail tracking

Supervisors Procurement Notes

Verify the specific suffix RL7 indicates reel packaging configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the SOT-23-6 footprint matches your PCB layout constraints. Validate that the fixed threshold voltages align with your target supply rails as no adjustable options exist for this variant.

Supervisors Selection Notes

Select this part when simultaneous monitoring of four standard voltage levels is required without complex programming. The fixed thresholds eliminate calibration needs compared to adjustable supervisors. Consider the 55 uA quiescent current for low-power design requirements. Verify that the open-drain output interface is compatible with your microcontroller reset input logic levels.

Supervisors Part Context

This component belongs to the ADM6339 series of quad voltage supervisors designed for robust power management in digital systems. Unlike single-channel monitors, it consolidates four detection channels into one small package. The JARJZ designation specifies the particular threshold combination and tape-and-reel packaging format used for automated assembly processes.

Supervisors Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Cross-reference with other ADM6339 variants only if threshold voltages match exactly. Verify pinout compatibility before attempting any physical substitution.
