ADM6339MARJZ-RL7

Supervisors Overview

The ADM6339MARJZ-RL7 is a quad voltage monitor manufactured by Analog Devices Inc., designed for supervisory applications. It operates within a supply voltage range up to 5.5 V and features an active low, open-drain output. The device includes a manual reset input and provides a fixed reset delay time of 200 ms. It supports four monitored inputs with specific threshold voltages of 1.23 V, 3.3 V, and 5 V. The component functions reliably across an operating temperature range from -40 C to +85 C and consumes a typical quiescent current of 55 uA.

Supervisors Feature Summary

• Provides simultaneous supervision of four independent voltage rails using dedicated input pins.
• Features a manual reset capability allowing external control over the reset state via a dedicated pin.
• Delivers a consistent reset signal after a fixed 200 ms delay to ensure stable power-up sequencing.
• Utilizes an active low open-drain output structure compatible with various logic families.

Supervisors Applications

• Multi-rail power system monitoring in embedded controllers
• Voltage supervision for industrial equipment power supplies
• Reset generation for microprocessor systems requiring multiple voltage levels

Supervisors Procurement Notes

Verify the exact suffix and package configuration against the manufacturer's latest datasheet before ordering. Confirm availability status as distribution channels may indicate limited stock or discontinuation. Ensure the selected variant matches the required threshold voltages and operating temperature range for your specific design constraints.

Supervisors Selection Notes

Select this component when a single IC must monitor four distinct voltage lines without requiring a watchdog timer. Consider the 55 uA quiescent current for battery-sensitive designs. Verify that the 5.5 V maximum supply voltage aligns with your highest rail. The SOT-23-6 package offers a compact footprint suitable for space-constrained PCB layouts.

Supervisors Part Context

This part belongs to the ADM6339 series of quad voltage monitors from Analog Devices. The series is characterized by its ability to handle multiple thresholds in a small surface-mount package. It serves as a cost-effective solution for systems needing comprehensive power integrity checks without complex digital interfaces.

Supervisors Replacement Considerations

Check for direct cross-references in distributor databases. Verify pin compatibility and electrical specifications if substituting with other quad supervisors. No official substitute part numbers are confirmed in the provided documentation.
