ADM6339DARJZ-RL7

Supervisors Overview

The ADM6339DARJZ-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 threshold voltages of 1.23 V, 1.58 V, 2.93 V, and 4.38 V. The device provides an active low, open-drain output and includes manual reset functionality with a fixed reset delay time of 200 ms. It does not include a watchdog timer or battery backup switch. The component draws a typical operating supply current of 55 uA and functions reliably across a temperature range from -40 C to +85 C.

Supervisors Feature Summary

• Monitors four distinct voltage rails simultaneously using dedicated input channels
• Provides active low open-drain status output for system integration
• Supports manual reset control via external push-button interface

Supervisors Applications

• Multi-rail power supply supervision in embedded systems
• Microprocessor reset generation in industrial controllers
• Voltage level monitoring in portable electronic devices

Supervisors Procurement Notes

Verify the exact suffix RL7 indicates reel packaging configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Check current lifecycle status as some variants may be subject to limited availability or obsolescence notices. Ensure compatibility with existing PCB footprint specifications for SOT-23-6 packages during replacement planning.

Supervisors Selection Notes

Select this variant when specific threshold combinations of 1.23 V, 1.58 V, 2.93 V, and 4.38 V are required for multi-voltage monitoring. Consider the 55 uA quiescent current for low-power applications. Verify that the absence of a watchdog timer meets system safety requirements. Ensure the active low open-drain output aligns with downstream logic interface needs.
