ADM8321WAW30ARJZR7

Supervisors Overview

The ADM8321WAW30ARJZR7 is a supervisory circuit from Analog Devices, housed in a 5-lead SOT-23 package. It features a 3.0 V threshold voltage and supports a maximum supply voltage of 5.5 V. The device provides an active high push-pull output with a manual reset function. It includes a watchdog timer with a 1.6 s timeout and a 200 ms timeout for the reset signal. The reset delay time is specified at 1.4 ms. Operating accuracy is 1.5%. The component operates within a temperature range of -40°C to +125°C.

Supervisors Feature Summary

• Integrates a watchdog timer with a 1.6-second timeout period for system monitoring.
• Provides a manual reset input for user-initiated system recovery.
• Delivers an active high push-pull output signal for direct logic interfacing.
• Operates reliably across an extended industrial temperature range.

Supervisors Applications

• Embedded systems requiring hardware-level supervision
• Microcontroller reset circuits
• Industrial control units

Supervisors Procurement Notes

Verify the exact suffix ARJZR7 against official Analog Devices documentation to confirm packaging and automotive grade specifications. Confirm availability status as distribution channels may list limited stock or special order conditions. Ensure the 3.0V threshold aligns with the target supply rail before procurement.

Supervisors Selection Notes

Select this component when a fixed 3.0V threshold is required for the monitored supply. The integrated watchdog timer eliminates external timing components. Verify that the active high push-pull output polarity matches the receiving logic interface requirements. Ensure the operating temperature range meets the environmental constraints of the final assembly.

Supervisors Part Context

This part belongs to the ADM8321 series of supervisory circuits designed for reliable power management. It combines voltage monitoring with watchdog functionality in a compact surface-mount package. The series is intended for applications requiring robust fault detection and automatic system recovery without complex software intervention.

Supervisors Replacement Considerations

Check for ADM8321 variants with different threshold voltages if the supply rail differs. Verify pin compatibility with other SOT-23-5 supervisors. Cross-reference specific suffix codes for temperature grades and packaging options to ensure functional equivalence.
