ADM8322WB26ARJZRL7

Supervisors Overview

The ADM8322WB26ARJZRL7 is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring microprocessor-based systems. It features a fixed reset threshold voltage of 2.62V and includes an integrated watchdog timer with selectable timeout options. The device provides a manual reset input capability and operates within a supply voltage range of 1.0V to 5.5V. It is housed in a compact SOT-23-5 package, suitable for surface-mount applications requiring reliable power management.

Supervisors Feature Summary

• Integrates a watchdog timer with multiple timeout selection options for system fault detection
• Includes a manual reset input pin allowing external control over the reset state
• Provides a push-pull or open-drain reset output stage compatible with various logic families

Supervisors Applications

• Microprocessor system supervision
• Controller board power monitoring
• Intelligent instrument reset management

Supervisors Procurement Notes

Verify the specific suffix configuration against the official datasheet to ensure correct threshold voltage and watchdog timeout settings. Confirm package type and reel specifications match design requirements. Check current availability status as distribution may vary by region. Ensure compatibility with existing PCB footprint and thermal constraints before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a fixed low-voltage threshold near 2.6V is required alongside active watchdog functionality. Consider the manual reset feature if external hardware intervention is needed during debugging. Evaluate the SOT-23-5 package size against available board space. Compare against other ADM63xx series variants if different thresholds or timeout periods are necessary for the specific application environment.

Supervisors Part Context

This part belongs to the ADM6316/ADM6317/ADM6318/ADM6319/ADM6320/ADM6321/ADM6322 family of supervisory circuits. These devices share common architectural features including watchdog timers and manual reset inputs but differ in reset thresholds and timeout durations. The ADM8322 specifically targets applications needing a ~2.6V threshold with flexible watchdog timing options.

Supervisors Replacement Considerations

Direct substitutes within the same family include ADM8321 (different threshold) or ADM8323 (different threshold). Verify that any replacement maintains the same SOT-23-5 package and electrical characteristics such as supply voltage range and output drive capability.
