ADM6320CZ29ARJ-RL7

Supervisors Overview

The ADM6320CZ29ARJ-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 watchdog timer and a manual reset input. It operates within a supply voltage range up to 5.5 V and provides an open-drain active-low reset output. The reset delay time is specified at 200 ms. It functions in temperatures from -40°C to +85°C and consumes 20 µA of operating current.

Supervisors Feature Summary

• Integrates a watchdog timer for system fault detection alongside power supply monitoring capabilities.
• Includes a dedicated manual reset input pin allowing for user-initiated system resets.
• Provides an open-drain active-low reset output stage suitable for interfacing with various logic families.

Supervisors Applications

• Microprocessor systems
• Controllers
• Intelligent instruments

Supervisors Procurement Notes

Verify the specific suffix 'RL7' against the manufacturer's official documentation to confirm reel packaging specifications and tape-and-reel dimensions. Ensure the component matches the required RoHS compliance status, as historical data indicates potential variations between leaded and lead-free versions within this series. Cross-reference the exact part number with the latest datasheet revision to validate all electrical parameters before procurement.

Supervisors Selection Notes

Select this component when a fixed 2.93 V threshold is required for low-voltage monitoring applications. The open-drain output configuration necessitates an external pull-up resistor; verify that the chosen resistor value aligns with the target logic voltage levels. Consider the 20 µA quiescent current if battery life is a critical design constraint compared to lower-power alternatives in the same family.

Supervisors Part Context

This part belongs to the ADM6320 series, which shares functional similarities with the ADM6316 through ADM6322 families. These devices are unified by their 5-lead SOT-23 package and integrated watchdog functionality. The specific model differs primarily in its reset threshold voltage and output stage configuration, distinguishing it from other variants like the ADM6320AX33ARJ-RL7 or ADM6320DY29ARJZ-R7.

Supervisors Replacement Considerations

Potential substitutes include ADM6320CY46ARJZ-R7 or ADM6320DY29ARJZ-R7, provided the reset threshold voltage requirements match the application design. Verify that the replacement maintains the open-drain output type and compatible watchdog timeout options.
