ADT7467ARQ-REEL7

Overview

The ADT7467ARQ-REEL7 is a complete thermal monitor and multiple fan controller designed for systems requiring precise thermal management. It integrates internal and external temperature sensing capabilities with an SMBus interface for digital communication. The device operates within a supply voltage range of 3 V to 5.5 V and supports an operating temperature range of -40°C to 120°C. It is housed in a 16-pin QSOP package, providing a compact solution for monitoring system temperatures and controlling cooling fans in microprocessor-based environments.

Feature Summary

• Integrates remote thermal monitoring with multiple fan control capabilities
• Supports both internal and external sensor inputs for comprehensive temperature tracking
• Features an SMBus digital interface for system integration

Applications

• Microprocessor-based system thermal management
• Remote thermal monitoring in computing equipment
• Fan speed control in server or workstation chassis

Procurement Notes

Verify the specific suffix 'REEL7' indicates tape-and-reel packaging when sourcing. Confirm the manufacturer origin, as this component has been associated with both Analog Devices and onsemi (formerly Linear Technology) due to corporate acquisitions. Ensure the datasheet matches the exact pinout and electrical specifications for the 16-QSOP variant to avoid compatibility issues with existing board designs.

Selection Notes

Select this component when a single IC must handle both temperature acquisition and active cooling control. It is suitable for applications requiring digital feedback via SMBus rather than analog outputs. Consider the 16-pin QSOP form factor for space-constrained designs that do not require surface-mount packages like TSSOP or SOIC. Verify that the required temperature range aligns with the -40°C to 120°C specification.

Part Context

This part belongs to the dBCool series of thermal management devices from Analog Devices. These components are engineered to simplify the design of cooling systems by combining sensing and actuation logic into a single chip. The ADT7467 specifically targets applications needing reliable temperature oversight and fan regulation without complex discrete circuitry.

Replacement Considerations

Check for direct substitutes such as the ADM1022 series for similar power supply support functions, though pinouts may differ. Verify if the ADT7468 offers necessary features if additional channels are required, noting it uses a 24-pin package. Always cross-reference the latest datasheets for any functional updates or pin reassignments.
