ADM8320WCZ33ARJZR7

Supervisors Overview

The ADM8320WCZ33ARJZR7 is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single-channel power supply voltages. It operates within a supply voltage range of 1.2 V to 5.5 V and features a fixed reset threshold voltage of 3.3 V. The device provides a push-pull active-low reset output with a typical timeout of 140 ms. It includes a manual reset input and an open-drain watchdog timer input, supporting windowed or non-windowed watchdog configurations. The component is rated for operation from -40°C to +125°C and is housed in a 5-lead SOT-23 package.

Supervisors Feature Summary

• Integrates a windowed watchdog timer with manual reset capability for enhanced system reliability.
• Provides a push-pull active-low reset output ensuring valid signals down to 1 V supply voltage.
• Features low power consumption suitable for battery-operated applications.
• Includes power supply glitch immunity to prevent false resets during transient events.

Supervisors Applications

• Portable electronic devices requiring reliable power supervision
• Automotive electronics systems operating under harsh environmental conditions
• Industrial control equipment needing robust voltage monitoring
• Communication infrastructure utilizing high-temperature components

Supervisors Procurement Notes

Verify the specific suffix ARJZR7 indicates reel packaging when ordering. Confirm the WCZ designation corresponds to the 3.3 V threshold variant. Ensure compatibility with surface-mount assembly processes for the SOT-23-5 package. Check for RoHS compliance status if required by regional regulations. Validate lead times as automotive-grade components may have extended availability periods.

Supervisors Selection Notes

Select this component when a fixed 3.3 V threshold is required for single-supply monitoring. Choose the push-pull output configuration for direct interfacing with digital logic without external pull-ups. Consider the wide temperature range for applications exceeding standard industrial limits. Evaluate the watchdog functionality needs against the available timeout options. Compare power consumption requirements against other supervisory circuits in the portfolio.
