ADT7468ARQZ

Overview

The ADT7468ARQZ is a board-mount thermal controller and voltage monitor manufactured by Analog Devices Inc. It features a digital output interface supporting I2C and SMBus protocols within a 24-lead QSOP package. The device operates across a temperature range of -40°C to +125°C with an accuracy of ±2°C. It supports remote temperature sensing configurations and integrates hardware monitoring capabilities for system thermal management.

Feature Summary

• Integrates remote thermal control and voltage monitoring functions
• Supports standard I2C and SMBus communication interfaces
• Provides high-accuracy digital temperature sensing

Applications

• Blade server fan monitoring and control
• System hardware health monitoring
• Thermal management in industrial equipment

Procurement Notes

Verify the specific manufacturer designation, as the ADT7468 series has been associated with both Analog Devices and onsemi in public records. Confirm the exact datasheet version and pinout compatibility before integration, as legacy documentation may vary between original manufacturers. Ensure the component meets current environmental compliance standards required for the target application.

Selection Notes

Select this component when a combined solution for remote temperature sensing and voltage monitoring is required. The I2C/SMBus interface simplifies integration into existing digital control systems. Consider the ±2°C accuracy specification against the thermal tolerance requirements of the monitored components to ensure reliable operation within the specified industrial temperature range.

Part Context

This part belongs to the ADT7468 family of thermal controllers. Similar devices in the series include the ADT7470ARQZ, which offers higher accuracy but fewer channels. The ADT7468ARQZ specifically targets applications requiring robust voltage monitoring alongside temperature regulation in compact surface-mount packages.
