ADM6339OARJZ-RL7

Supervisors Overview

The ADM6339OARJZ-RL7 is a quad voltage microprocessor supervisory circuit manufactured by Analog Devices Inc. It monitors four independent supply rails using fixed threshold voltages of 1.23 V, 3.3 V, and 5 V. The device features an active low, open-drain reset output with a manual reset input and a 200 ms reset delay time. It operates within a supply voltage range up to 5.5 V and consumes 55 uA of quiescent current. The component is housed in a compact SOT-23-6 surface-mount package and functions reliably across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Monitors four independent power supply rails simultaneously
• Provides active low open-drain reset signal generation
• Includes manual reset input for system control
• Operates with low quiescent current consumption

Supervisors Applications

• Multi-rail power supply monitoring in embedded systems

Supervisors Procurement Notes

Verify the specific suffix RL7 indicates reel packaging configuration when ordering. Confirm the exact threshold voltage combination matches the OARJZ variant specifications. Ensure compatibility with existing PCB footprint designs utilizing the SOT-23-6 package. Check for any end-of-life notices or obsolescence warnings from the manufacturer before finalizing procurement plans.

Supervisors Selection Notes

Select this component when simultaneous monitoring of four distinct voltage levels is required without external comparator complexity. The fixed thresholds simplify design compared to adjustable variants. Consider the 200 ms delay requirement against system startup timing needs. Verify that the open-drain output interface aligns with the downstream logic level requirements of the monitored processor or controller.
