ADM6339FARJZ-RL7

Supervisors Overview

The ADM6339FARJZ-RL7 is a quad voltage microprocessor supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 1.2V to 5.5V and features four independent voltage monitor inputs with thresholds of 1.23V, 2.0V, and 3.0V. The device provides an active-low open-drain reset output with a fixed 200ms reset delay. It includes a manual reset input and supports operation across an extended temperature range from -40°C to +85°C. The component is housed in a compact SOT-23-6 package and consumes a typical quiescent current of 55µA.

Supervisors Procurement Notes

Verify the specific suffix configuration against official Analog Devices documentation to ensure correct threshold voltages and package type. Confirm RoHS compliance status and lead times through authorized distributors as availability may vary. Cross-reference the full part number including reel specifications to match manufacturing batch requirements.

Supervisors Selection Notes

Select this component when multiple voltage rails require simultaneous supervision within a single IC footprint. Ensure the required threshold voltages align with the available factory-set options or adjustable configurations. Verify that the active-low output polarity matches the target processor reset pin requirements before integration into the design.

Supervisors Part Context

This part belongs to the ADM6339 series of quad voltage supervisors designed for complex digital systems. It consolidates multiple discrete monitoring functions into a single small outline transistor package. The series offers various threshold combinations to accommodate different logic families and power rail standards commonly found in modern electronic designs.

Supervisors Replacement Considerations

Compatible substitutes include other ADM6339 variants with matching pinout and package dimensions. Verify that alternative parts support the same four-input architecture and active-low reset output characteristics. Check thermal performance and operating voltage ranges to ensure equivalence in the intended application environment.
