ADM6339QARJZ-RL7

Supervisors Overview

The ADM6339QARJZ-RL7 is a quad voltage monitor from Analog Devices, housed in an SOT-23-6 surface-mount package. It features four independent monitoring inputs with one fixed threshold at 3.3 V and three adjustable thresholds. The device provides active low open-drain reset outputs with a standard 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 supports manual reset functionality without watchdog or battery backup switches, functioning reliably across an industrial temperature range of -40 C to +85 C.

Supervisors Feature Summary

• Provides simultaneous supervision of four distinct power rails using dedicated input channels.
• Offers flexible threshold configuration through three adjustable voltage inputs alongside a fixed 3.3 V reference.
• Delivers system reset signals via active low open-drain outputs compatible with various logic families.
• Integrates a manual reset pin allowing external control over the reset state generation.

Supervisors Applications

• Multi-rail power sequencing in embedded computing systems
• Voltage supervision for portable electronic devices
• Industrial control board power integrity monitoring

Supervisors Procurement Notes

Verify component authenticity due to end-of-life status. Confirm specific lot codes against manufacturer records. Check for obsolescence notices from Analog Devices. Ensure storage conditions meet moisture sensitivity levels. Validate packaging integrity upon receipt.

Supervisors Selection Notes

Evaluate if adjustable thresholds meet precise rail requirements compared to fixed alternatives. Consider the 200 ms delay duration for system startup timing constraints. Assess the SOT-23-6 footprint compatibility with existing PCB layouts. Verify that the open-drain output structure suits the downstream logic interface needs.

Supervisors Part Context

This part belongs to the ADM6339 series of quad voltage supervisors. It shares the core architecture with variants like ADM6339PARJZ-RL7 but differs in threshold configurations. The Q suffix indicates specific adjustable threshold options. It serves as a compact solution for multi-voltage monitoring in space-constrained designs.

Supervisors Replacement Considerations

Check for ADM6339PARJZ-RL7 or ADM6339KARJZ-RL7 if threshold values align. Verify pinout compatibility before substitution. Confirm electrical specifications match application requirements exactly.
