ADM6320CY46ARJZ-R7

Supervisors Overview

The ADM6320CY46ARJZ-R7 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 overvoltage threshold of 4.699 V. The device operates within a supply voltage range up to 5.5 V and consumes 20 uA of working power current. It provides a manual reset input and utilizes an open-drain output type. The reset delay time is specified at 200 ms with an accuracy of 2.5%. The component is housed in a SOT-23-5 package and supports surface mount installation.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Includes a dedicated manual reset input for user control
• Provides open-drain active low reset output stage
• Ensures power supply glitch immunity

Supervisors Applications

• Microprocessor systems
• Controllers
• Intelligent instruments

Supervisors Procurement Notes

Verify the specific suffix ARJZ-R7 against the manufacturer datasheet to confirm the exact threshold voltage and packaging configuration. Ensure compatibility with the target PCB footprint for the SOT-23-5 package. Confirm RoHS compliance status if required by project specifications. Cross-reference the part number with official Analog Devices documentation to validate all electrical parameters before integration.

Supervisors Selection Notes

Select this component when a fixed 4.63 V threshold is required for single-channel power supply management. The inclusion of a manual reset input distinguishes it from variants lacking this feature. Consider the 20 uA quiescent current for low-power applications. Verify that the open-drain output architecture aligns with the downstream logic requirements of the design.

Supervisors Part Context

This part belongs to the ADM6320 series of supervisory circuits manufactured by Analog Devices. The series offers various threshold options and output configurations. The CY46 designation indicates the specific 4.63 V threshold variant. The R7 suffix typically denotes reel packaging for automated assembly processes.

Supervisors Replacement Considerations

ADM6320CZ46ARJZ-R7: Offers identical functionality but may differ in lead-free compliance status compared to the CY variant.
