ADM8320WCZ29ARJZR7

Supervisors Overview

The ADM8320WCZ29ARJZR7 is a supervisory circuit manufactured by Analog Devices Inc., designed for power supply management in automotive applications. It features a single channel with a reset threshold voltage of 2.93V and an active-low open-drain output. The device includes a manual reset input and operates within a temperature range of -40°C to 125°C. Packaged in a surface-mount SOT-23-5 case, it provides reliable monitoring with a minimum reset timeout of 140ms.

Supervisors Feature Summary

• Integrated manual reset input for system control
• Automotive-grade reliability specification
• Active-low open-drain reset output configuration

Supervisors Applications

• Automotive electronic systems monitoring
• Microcontroller power supply supervision
• Embedded system reset management

Supervisors Procurement Notes

Verify the exact suffix 'WCZ' against official Analog Devices documentation to confirm package type and temperature grade alignment. Ensure compatibility with existing PCB footprints for the SOT-23-5 form factor. Cross-reference the specific revision level to guarantee functional equivalence with current production units. Confirm that the open-drain output interface matches the target microcontroller or logic gate requirements for proper pull-up implementation.

Supervisors Selection Notes

Select this component when a low-cost, single-channel supervisor with manual reset capability is required for automotive environments. The 2.93V threshold suits 3.3V logic systems. Consider the open-drain output if wired-OR configurations are needed. Verify that the 140ms minimum timeout meets the startup sequence requirements of the protected circuitry. Ensure the operating temperature range covers the intended application environment.
