ADM6320CZ27ARJZ-R7

Supervisors Overview

The ADM6320CZ27ARJZ-R7 is a supervisory circuit manufactured by Analog Devices Inc., designed for power supply management. It operates within a maximum supply voltage of 5.5 V and features a fixed reset threshold voltage of 2.7 V with an accuracy of 2.5%. The device incorporates a watchdog timer and a manual reset input, providing robust system protection. It utilizes an open-drain output type and offers a reset delay time of 200 ms. The component functions in a single-input configuration without battery backup switching or chip enable signals. It consumes 20 uA of operating current and is housed in a SOT-23-5 package, suitable for surface mount installation across an industrial temperature range from -40 C to +85 C.

Supervisors Feature Summary

• Integrates a watchdog timer and manual reset input for comprehensive system supervision
• Features an open-drain active-low reset output stage
• Provides power supply glitch immunity and low power consumption
• Ensures reset output validity down to a minimum supply voltage

Supervisors Applications

• Embedded systems requiring reliable power monitoring
• Microcontroller-based designs needing watchdog functionality
• Industrial equipment operating in harsh environments
• Portable devices utilizing low-power supervisory circuits

Supervisors Procurement Notes

Verify the specific suffix ARJZ-R7 to confirm the reel packaging format and exact threshold voltage variant. Ensure compatibility with the target PCB footprint for the SOT-23-5 package. Confirm that the open-drain output configuration aligns with the downstream logic requirements. Check for RoHS compliance documentation if required by regulatory standards. Validate the operating temperature range against the intended application environment.

Supervisors Selection Notes

Select this component when a fixed 2.7 V threshold is required for the monitored rail. Consider the 200 ms reset delay and open-drain output characteristics during interface design. Evaluate the 20 uA quiescent current against total system power budgets. Verify that the manual reset pin can be adequately utilized for user intervention or external triggering. Ensure the industrial temperature rating meets the operational constraints.

Supervisors Part Context

This part belongs to the ADM6320 series of supervisory circuits from Analog Devices. The series offers various threshold voltages and timeout options to suit different power management needs. The ADM6320 family is characterized by its compact 5-lead SOT-23 package and integrated watchdog features. It serves as a critical component for ensuring system stability in voltage-sensitive applications.

Supervisors Replacement Considerations

Cross-reference with other ADM6320 variants sharing the same SOT-23-5 package and open-drain output. Verify that substitute parts match the 2.7 V threshold and 200 ms reset delay specifications. Ensure equivalent operating temperature ranges and supply voltage limits are maintained.
