ADM6320CY29ARJ-RL7

Supervisors Overview

The ADM6320CY29ARJ-RL7 is a supervisory circuit from Analog Devices, designed for monitoring microprocessor-based systems. It features a fixed reset threshold voltage of 2.93 V with an accuracy of 2.5%. The device includes a manual reset input and an open-drain active low reset output stage. It operates within a supply voltage range up to 5.5 V and consumes 20 uA of working power current. The component provides a reset delay time of 200 ms and supports a watchdog timer function. It is housed in a 5-lead SOT-23 package and functions reliably across an industrial temperature range from -40 C to +85 C.

Supervisors Feature Summary

• Integrates a watchdog timer for system fault detection alongside voltage supervision capabilities.
• Includes a dedicated manual reset input allowing for user-initiated system resets.
• Provides an open-drain active low reset output stage compatible with various logic families.

Supervisors Applications

• Microprocessor systems
• Controllers
• Intelligent instruments

Supervisors Procurement Notes

Verify the specific suffix 'CY' corresponds to the required 2.93 V threshold and open-drain output configuration. Confirm RoHS compliance status as documentation varies between leaded and lead-free variants. Ensure the SOT-23-5 package footprint matches the design constraints. Cross-reference the manufacturer part number against official Analog Devices databases to validate availability and revision history before finalizing procurement.

Supervisors Selection Notes

Select this component when a fixed 2.93 V threshold is required for single-channel power supply monitoring. The inclusion of a manual reset input makes it suitable for applications requiring both automatic supervision and user intervention. The open-drain output allows for flexible interfacing with different logic levels. Consider the 20 uA quiescent current for low-power designs operating within the specified industrial temperature range.

Supervisors Part Context

This part belongs to the ADM6316/ADM6317/ADM6318/ADM6319/ADM6320/ADM6321/ADM6322 family of supervisory circuits. These devices are engineered to monitor voltage levels and provide reset signals for digital systems. The family offers various threshold options and output configurations to suit diverse application requirements while maintaining a compact 5-lead SOT-23 form factor.

Supervisors Replacement Considerations

Check for ADM6320 variants with different threshold codes (e.g., CZ for 2.93 V) if exact suffix matching is unavailable. Verify pinout compatibility with other ADM6320 series parts. Ensure replacement components match the open-drain output type and manual reset functionality.
