ADT7463ARQZ-REEL

Overview

The ADT7463ARQZ-REEL is a board-mount temperature sensor IC manufactured by onsemi. It operates within a supply voltage range of 2.7 V to 5.5 V and supports digital output via I2C or SMBus interfaces. The device provides high accuracy with a maximum error of ±0.5°C across an operating temperature range of -40°C to +125°C. It features a 10-bit resolution and includes remote temperature sensing capabilities. The component is housed in a QSOP-16 package and is designed for surface mount installation.

Feature Summary

• High measurement accuracy with ±0.5°C maximum error
• Supports I2C and SMBus digital communication protocols
• Enables remote temperature sensing for external components
• Operates reliably across extended industrial temperature ranges

Applications

• System management controller thermal monitoring
• Server and storage enclosure temperature tracking
• Industrial equipment thermal protection circuits

Procurement Notes

Verify the specific suffix REEL against official onsemi documentation to confirm tape-and-reel packaging specifications. Confirm current lifecycle status as the product may be discontinued or subject to limited availability. Ensure interface compatibility with existing system controllers before procurement. Check for any recent PCN updates regarding material or labeling changes.

Selection Notes

Select this component when precise thermal monitoring is required for system management applications. The integrated remote sensing capability allows for accurate measurement at distant points. Verify that the host controller supports the required I2C or SMBus protocol speeds. Consider the QSOP-16 package constraints during PCB layout design to ensure proper thermal dissipation and mechanical fit.

Part Context

This part belongs to the ADT746x series of hardware monitors and thermal sensors from onsemi. These devices are engineered for comprehensive system health monitoring, combining temperature acquisition with control logic.
