ADM1027ARQ

Overview

The ADM1027ARQ is a dBCOOL remote thermal controller and voltage monitor manufactured by Analog Devices Inc. It integrates multiple PWM fan control capabilities with comprehensive system monitoring functions, designed for noise-sensitive applications requiring active cooling. The device supports both internal and external temperature sensing within a range of 0°C to 105°C. It features an SMBus interface for communication and includes standby mode functionality. The component is housed in a 24-pin QSOP package.

Feature Summary

• Integrates complete systems monitoring with multiple PWM fan control for active cooling management
• Supports both internal and external temperature sensing for precise thermal regulation
• Features SMBus interface for digital communication and system integration

Applications

• Noise-sensitive computer systems requiring active cooling
• Microprocessor-based system thermal management
• Server and workstation environmental monitoring

Procurement Notes

Verify the specific suffix 'ARQ' corresponds to the 24-QSOP package variant when sourcing. Confirm RoHS compliance status as documentation indicates non-compliance for this specific part number. Ensure the supplier provides original manufacturer packaging to prevent damage during transit. Validate that the received unit matches the active product status listed by Analog Devices.

Selection Notes

Select this component for applications demanding integrated thermal control and voltage monitoring in a single IC. It is suitable for designs where space constraints favor a multi-function controller over discrete sensors and drivers. Consider the 24-pin QSOP package availability against board layout requirements. Evaluate the need for external temperature sensing capabilities alongside internal monitoring.

Part Context

This part belongs to the ADM1027 family of dBCOOL controllers from Analog Devices. These devices are engineered for low-noise computing environments. The family typically combines fan control logic with sensor interfaces. The ARQ designation specifies the plastic quad small-outline package configuration used in this variant.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing firmware or control algorithms if considering alternative thermal controllers from other manufacturers.
