ADT7468ARQZ-REEL

Thermal Management Overview

The ADT7468ARQZ-REEL is a board-mount thermal controller and voltage monitor manufactured by Analog Devices Inc. It operates within a supply voltage range of 3V to 5.5V and supports I2C, SMBus, and 2-Wire interfaces. The device features remote temperature sensing with an accuracy of +/- 2°C across a working temperature range of -40°C to +120°C. It is housed in a 24-QSOP package and includes internal and external sensor topology with fan control capabilities.

Thermal Management Feature Summary

• Integrates remote thermal control with voltage monitoring functions
• Supports multiple digital communication protocols including I2C and SMBus
• Provides precise remote temperature sensing with specified accuracy

Thermal Management Applications

• Server and storage system thermal management
• Industrial equipment temperature monitoring
• Telecommunications infrastructure cooling control

Thermal Management Procurement Notes

Verify the manufacturer designation carefully, as the ADT7468 series was originally developed by Analog Devices but is now distributed or produced under onsemi branding. Confirm the specific datasheet revision and pinout compatibility for your design. Ensure the QSOP-24 package matches your PCB footprint requirements before procurement.

Thermal Management Selection Notes

Select this component when integrated thermal regulation and voltage supervision are required in a single IC. It is suitable for designs needing remote sensor support and fan speed control via digital interfaces. Consider the operating temperature range and interface compatibility with your host microcontroller or system bus.

Thermal Management Part Context

This part belongs to the ADT7468 series of hardware monitors. It combines analog-to-digital conversion, comparator logic, and fan speed counting into one unit. The series is designed for comprehensive thermal management in high-density electronic systems requiring reliable temperature tracking and active cooling control.

Thermal Management Replacement Considerations

Check for ADT7468ARQZ without the reel suffix if tape-and-reel packaging is not required. Verify cross-brand equivalents from onsemi if Analog Devices stock is unavailable, ensuring functional and pinout compatibility.
