ADT7460ARQ-REEL7

Overview

The ADT7460ARQ-REEL7 is a dBCOOL remote thermal controller and fan controller designed for noise-sensitive applications. It monitors up to two remote sensor diodes plus its internal temperature, controlling up to four fans at minimum speeds for acoustic optimization. The device features dynamic TMIN control, automatic fan speed adjustment based on measured temperature, and enhanced acoustic modes. It includes thermal protection via the bidirectional THERM pin and supports SMBus 2.0 electrical specifications.

Feature Summary

• Controls and monitors up to four fan speeds with automatic speed control based on measured temperature
• Features dynamic TMIN control mode to intelligently optimize system acoustics and cooling
• Includes one on-chip and two remote temperature sensors with limit comparison capabilities
• Provides thermal protection via the bidirectional THERM output and monitors Intel Pentium 4 processor thermal control

Applications

• Low acoustic noise PCs
• Networking equipment
• Telecommunications equipment

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix matches the required reel packaging configuration. Check for RoHS compliance status and ensure the device meets current environmental regulations for your region. Validate that the part number corresponds to the exact revision level required for your design integration.

Selection Notes

Select this component for systems requiring active cooling with strict acoustic constraints. Ensure the application utilizes an SMBus interface for configuration and monitoring. Verify that the power supply voltage range aligns with the system's available rails. Consider the pinout requirements for remote diode connections and fan tachometer inputs during PCB layout planning.

Part Context

This part belongs to the ADT7460 series of thermal management controllers. It is manufactured by Analog Devices, now often associated with onsemi in certain distribution contexts. The device integrates analog-to-digital conversion, fan speed counting, and PWM generation into a single QSOP package, simplifying thermal management designs.

Replacement Considerations

Check for ADT7460 variants with different packaging or address configurations. Verify compatibility with existing SMBus addresses if multiple units are used. Ensure substitute parts support the same remote diode sensing accuracy and fan control logic.
