ADM6339CARJZ-RL7

Supervisors Overview

The ADM6339CARJZ-RL7 is a quad voltage microprocessor supervisory circuit manufactured by Analog Devices Inc. It monitors four independent supply voltages and asserts an active-low open-drain reset signal when any monitored input falls below its respective threshold. The device features a manual reset input, a fixed 200 ms reset delay time, and operates within a supply voltage range up to 5.5 V. It draws 55 uA of operating current and functions across a temperature range of -40 C to +85 C. The component is housed in a SOT-23-6 package.

Supervisors Feature Summary

• Monitors four independent voltage rails with dedicated thresholds
• Provides active-low open-drain reset output with 200 ms delay
• Includes manual reset input for system control
• Operates with low quiescent current consumption

Supervisors Applications

• Multi-rail power supply monitoring in embedded systems
• Microprocessor reset generation in industrial controllers
• Voltage supervision in communication equipment
• Power management in automotive electronics

Supervisors Procurement Notes

Verify the specific threshold voltages for the CARJZ suffix against the official datasheet, as variations exist within the ADM6339 family. Confirm availability status directly with Analog Devices or authorized distributors, as this part may be subject to limited supply or end-of-life conditions. Ensure the SOT-23-6 package compatibility matches your PCB design requirements before procurement.

Supervisors Selection Notes

Select this component when simultaneous monitoring of four distinct voltage levels is required without external comparator circuits. The fixed 200 ms delay suits applications where rapid transient rejection is not critical. Consider the 55 uA quiescent current for battery-powered designs. Verify that the manual reset feature aligns with your system's recovery logic needs.

Supervisors Part Context

The ADM6339 series comprises quad voltage supervisors designed for robust power system oversight. The CARJZ variant specifically denotes a particular set of threshold voltages and packaging configuration within the broader ADM6339 family. This series is intended for applications requiring reliable reset generation under varying power conditions.

Supervisors Replacement Considerations

Check for ADM6339 variants with similar threshold configurations if exact replacement is unavailable. Cross-reference pinouts and electrical characteristics with other quad supervisors from Analog Devices or competitors like ON Semiconductor or RICOH, ensuring functional equivalence in reset behavior and monitoring capabilities.
