ADM6320CY46ARJ-RL7

Supervisors Overview

The ADM6320CY46ARJ-RL7 is a supervisory circuit from Analog Devices, designed for monitoring microprocessor-based systems. It features a fixed reset threshold voltage of 4.63 V and an open-drain active low output stage. The device includes a manual reset input and a watchdog timer with a typical timeout of 1600 ms. It operates within a supply voltage range up to 5.5 V and consumes 20 uA of quiescent current. The component is specified over an industrial temperature range of -40°C to +85°C and is housed in a 5-lead SOT-23 package.

Supervisors Feature Summary

• Integrates a watchdog timer and manual reset input for comprehensive system supervision
• Provides an open-drain active low reset output stage
• Ensures power supply glitch immunity and valid reset output down to 1 V
• Operates within the industrial temperature range of -40°C to +85°C

Supervisors Applications

• Microprocessor systems
• Controllers
• Intelligent instruments

Supervisors Procurement Notes

Verify the specific suffix ARJZ against the official datasheet to confirm the exact threshold voltage and package variant. Ensure the order matches the required RoHS compliance status, as non-compliant versions exist within the same family. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Supervisors Selection Notes

Select this component when a fixed 4.63 V threshold is required for single-channel power supply monitoring. The open-drain output allows for flexible interfacing with various logic levels. Consider the 20 uA quiescent current for low-power applications. Verify that the 1600 ms watchdog timeout meets the system's timing requirements.

Supervisors Part Context

This part belongs to the ADM6320 series of supervisory circuits. The series offers multiple threshold options and output configurations. The CY46 suffix indicates the specific 4.63 V threshold voltage. The RJZ suffix typically denotes the SOT-23-5 package and RoHS compliance. Other variants in the series differ by threshold voltage and output type.

Supervisors Replacement Considerations

Direct replacements include other ADM6320 variants with different thresholds or output stages, such as ADM6320AX33ARJ-RL7 (3.3V) or ADM6320CZ29ARJ-RL7 (2.93V). Ensure the replacement maintains the open-drain output and manual reset functionality if required.
