ADM6339KARJZ-RL7

Supervisors Overview

The ADM6339KARJZ-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 consumes 55 uA of quiescent current. The device features four monitored inputs with threshold voltages of 1.23 V, 2.19 V, and 2.93 V. It provides an active low, open drain output with a manual reset capability and a fixed reset delay time of 200 ms. The component supports overvoltage detection thresholds including adjustable and fixed values such as 3 V and 2.25 V. It is housed in a SOT-23-6 package and functions reliably across an operating temperature range from -40 C to +85 C.

Supervisors Feature Summary

• Monitors four independent voltage rails simultaneously using dedicated input pins
• Provides manual reset functionality for controlled system recovery
• Delivers active low open drain output signals for logic interface compatibility
• Integrates a fixed 200 ms reset delay timer to ensure stable power sequencing

Supervisors Applications

• Embedded systems requiring multi-rail power supervision
• Industrial control units monitoring critical voltage levels
• Communication equipment ensuring stable power delivery
• Consumer electronics with multiple internal power domains

Supervisors Procurement Notes

Verify the exact suffix RL7 indicates reel packaging configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Check current lifecycle status as some variants may be subject to limited availability or end-of-life notices. Ensure the specific threshold voltage combination matches the target application requirements before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when simultaneous monitoring of four distinct voltage rails is required within a compact footprint. The SOT-23-6 package offers space efficiency for dense PCB layouts. Consider the 55 uA quiescent current for battery-powered applications where low standby consumption is critical. Verify that the available threshold voltages align precisely with the system's power rail specifications to avoid false triggering or missed faults.

Supervisors Part Context

This part belongs to the ADM6339 series of quad voltage monitors from Analog Devices. The series is designed for applications needing comprehensive power management supervision. Variants within the family differ primarily in preset threshold voltages and package options. The K suffix typically denotes specific threshold configurations compared to other letters in the naming convention.

Supervisors Replacement Considerations

Direct substitutes include other ADM6339 variants with compatible pinouts but different threshold settings. Cross-reference datasheets to ensure electrical parameters match the original design requirements. Verify package compatibility and thermal characteristics when considering alternative manufacturers.
