ADM6339BARJZ-RL7

Supervisors Overview

The ADM6339BARJZ-RL7 is a quad voltage microprocessor supervisory circuit manufactured by Analog Devices Inc. It monitors four independent supply voltages and provides reset signals when thresholds are exceeded. The device features an active low, open-drain output and supports manual reset functionality. It operates within a supply voltage range up to 5.5 V and consumes 55 uA of quiescent current. The reset delay time is fixed at 200 ms. The component is housed in a compact SOT-23-6 surface-mount package and is rated for operation between -40°C and +85°C.

Supervisors Feature Summary

• Monitors four independent voltage rails simultaneously
• Provides active low open-drain reset outputs
• Includes manual reset input capability
• Operates with low quiescent current consumption

Supervisors Applications

• Multi-rail power system supervision
• Microprocessor board voltage monitoring
• Embedded system power integrity verification
• Industrial control unit power management

Supervisors Procurement Notes

Verify the specific threshold voltage configuration required for your design, as the BAR suffix denotes a fixed set of predetermined thresholds distinct from other variants in the ADM6339 family. Confirm availability status directly with authorized distributors or the manufacturer, as supply constraints may apply. Ensure the SOT-23-6 package footprint matches your PCB layout requirements before finalizing procurement orders.

Supervisors Selection Notes

Select this component when simultaneous monitoring of four distinct voltage levels is necessary without external comparator circuits. The fixed threshold configuration simplifies design validation compared to adjustable variants. Consider the 200 ms reset delay and 55 uA current draw against system power budgets and timing requirements. Verify that the active low open-drain output interface is compatible with the target processor's reset input logic levels.

Supervisors Part Context

The ADM6339BARJZ-RL7 belongs to the ADM6339 series of quad voltage supervisory circuits. This series is designed for applications requiring comprehensive power rail monitoring in compact form factors. The part number indicates a specific threshold configuration variant within the broader family, differentiated by letter codes such as A, B, C, D, etc., which define the monitored voltage levels.

Supervisors Replacement Considerations

Direct replacements include other ADM6339 variants with matching SOT-23-6 packaging and similar electrical characteristics, provided the threshold voltages align with system requirements. Cross-referencing datasheets is essential to ensure compatibility of reset delays, quiescent current, and output drive capabilities.
