ADM8322WC46ARJZR7

Supervisors Overview

The ADM8322WC46ARJZR7 is a supervisory circuit from Analog Devices Inc. designed for monitoring microprocessor-based systems. It features a fixed reset threshold voltage of 4.63 V and operates within a supply voltage range up to 5.5 V. The device includes an integrated watchdog timer with multiple timeout options and a manual reset input. It utilizes a push-pull output stage and is housed in a compact SOT-23-5 package. The component supports an extended industrial temperature range from -40°C to +125°C, ensuring reliable performance in demanding environments.

Supervisors Feature Summary

• Integrates a windowed watchdog timer with selectable timeout periods to detect software malfunctions.
• Provides a manual reset input allowing external control over the system reset state.
• Features a push-pull reset output stage capable of driving loads directly without additional pull-up components.

Supervisors Applications

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

Supervisors Procurement Notes

Verify the specific suffix 'WC46' corresponds to the required 4.63V threshold and temperature grade during procurement. Confirm the 'R7' suffix indicates reel packaging if tape-and-reel handling is required. Ensure compatibility with the target application's voltage levels and thermal constraints before finalizing orders.

Supervisors Selection Notes

Select this part when a fixed 4.63V threshold is required alongside active watchdog functionality. The push-pull output is suitable for applications needing direct drive capability. Consider the -40°C to +125°C operating range for industrial or automotive-grade deployments where standard commercial parts may be insufficient.

Supervisors Part Context

This component belongs to the ADM832x series of high-temperature supervisory circuits. These devices are engineered to provide robust power management and system protection for embedded applications. The series offers various threshold voltages and output configurations to suit different design requirements while maintaining a small footprint.

Supervisors Replacement Considerations

ADM8322WB46ARJZR7: Offers identical electrical specifications but features an open-drain output instead of push-pull. Verify if the application circuit can support open-drain requirements or requires the active drive of the original part.
