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 asserts an active-low reset signal when any monitored voltage falls below its respective threshold. The device features a manual reset input, an open-drain output structure, and a fixed 200 ms reset delay timer. It operates within a supply voltage range up to 5.5 V with a typical quiescent current of 55 uA. The component is housed in a compact SOT-23-6 surface-mount package and supports operation across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Monitors four independent power supply rails simultaneously for system integrity
• Provides a synchronized active-low reset output with a fixed 200 ms delay
• Includes a manual reset input pin for external control capability
• Utilizes low-power architecture suitable for battery-operated applications

Supervisors Applications

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

Supervisors Procurement Notes

Verify the specific suffix 'BARJZ' against the manufacturer's latest datasheet to confirm exact threshold voltages and package variations. Confirm RoHS compliance status and lead times directly with authorized distributors as availability may vary. Ensure the ordering information matches the required electrical specifications for your design.

Supervisors Selection Notes

Select this component when simultaneous monitoring of four distinct voltage levels is required without external logic. Verify that the internal thresholds align with the target supply rails. Consider the SOT-23-6 footprint constraints and the open-drain output requirements for pull-up resistor selection in the final circuit design.

Supervisors Part Context

This part belongs to the ADM6339 family of quad voltage supervisors. It shares common functional characteristics with other variants in the series, differing primarily in preset threshold values and package options. The family is designed for general-purpose microprocessor reset generation in multi-voltage environments.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the ADM6339 series or comparable quad supervisors from other manufacturers. Verify threshold voltage compatibility and package dimensions before substitution.
