ADT7475ARQZ

Overview

The ADT7475ARQZ is a remote thermal monitor and fan controller manufactured by onsemi. It operates within a supply voltage range of 3 V to 3.6 V and supports an operating temperature range from -40°C to +125°C. The device features an SMBus digital output interface and utilizes a 16-SSOP package with dimensions of 0.154 inches (3.90 mm) width. It provides internal and external sensor monitoring capabilities with a maximum accuracy of ±1.5°C.

Feature Summary

• Integrates remote thermal monitoring and fan control functions for system management
• Supports both internal and external temperature sensing configurations
• Communicates via SMBus digital output interface

Applications

• Server and storage system thermal management
• Workstation hardware monitoring
• Industrial equipment temperature control

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific revision level matches design requirements, as legacy Analog Devices parts transitioned to onsemi. Ensure compliance with RoHS directives and check moisture sensitivity levels for surface mount assembly processes. Validate package integrity upon receipt.

Selection Notes

Select this component when integrated fan speed control and remote thermal monitoring are required in a compact footprint. The 16-SSOP package suits space-constrained designs. Verify that the 3 V to 3.6 V supply voltage aligns with the target system architecture. Consider the ±1.5°C accuracy specification against application thermal tolerance requirements.

Part Context

This part belongs to the dbCOOL series of thermal controllers. Originally developed by Analog Devices, production was transferred to onsemi. It serves as a dedicated solution for managing cooling systems in computing infrastructure, replacing discrete monitoring components with a single integrated circuit.
