ADM6320CZ29ARJZ-R7

Supervisors Overview

The ADM6320CZ29ARJZ-R7 is a single-channel power supply management circuit manufactured by Analog Devices Inc. It operates within an industrial temperature range of -40 °C to +85 °C and is housed in a 5-pin PDSO5 package, specifically identified as SOT-23 or LSSOP with dimensions of 2.9 mm length. The device features a fixed reset threshold voltage of 2.93 V and includes a manual reset input. It is RoHS compliant and lead-free, classified under ECCN code EAR99.

Supervisors Feature Summary

• Integrates a watchdog timer for system monitoring alongside standard supervisory functions
• Provides a dedicated manual reset input for user-initiated system control
• Features an open-drain active-low reset output stage suitable for various logic levels

Supervisors Applications

• Microprocessor-based systems requiring reliable power supervision
• Controllers needing integrated watchdog functionality
• Intelligent instruments demanding low-power monitoring solutions

Supervisors Procurement Notes

Verify the specific suffix 'CZ' indicates the commercial temperature grade variant when sourcing replacements. Confirm the 'R7' designation corresponds to the reel packaging format required for automated assembly processes. Ensure the part number matches the exact 2.93 V threshold specification to avoid functional mismatches in existing designs.

Supervisors Selection Notes

Select this component when a fixed 2.93 V threshold is required for the monitored rail. The open-drain output configuration allows flexibility in interfacing with different logic families. Consider the industrial temperature rating if the application environment exceeds standard commercial limits, ensuring reliability across the specified operating range.

Supervisors Part Context

This part belongs to the ADM6316/ADM6320 series of supervisory circuits from Analog Devices. These devices are designed to monitor microprocessor systems, offering options for various reset thresholds and timeout periods. The ADM6320 variant specifically combines power-supply monitoring with a watchdog timer and manual reset capability in a compact five-lead package.

Supervisors Replacement Considerations

Direct substitutes include other ADM6320 variants with matching 2.93 V thresholds, such as ADM6320DY29ARJZ-R7. Verify that replacement parts maintain the same open-drain output polarity and package footprint to ensure compatibility without board redesign.
