ADM1034ARQZ-REEL7

Overview

The ADM1034ARQZ-REEL7 is a thermal monitor and fan speed controller manufactured by onsemi. It integrates one local and two remote temperature sensing channels with ±1°C accuracy. The device features dual-channel fan speed control using a look-up table for temperature-to-fan speed profiles in linear or discrete modes. It communicates via an SMBus 2.0 interface, supports up to 64 measurements per second, and operates within a 3.0 V to 5.5 V supply range.

Feature Summary

• Dual-channel fan speed control with programmable look-up tables for linear or discrete operation
• Integrated local and remote temperature monitoring with high accuracy
• SMBus 2.0 interface with address resolution protocol support
• Configurable overtemperature alerts and fan fault detection outputs

Applications

• Desktop and notebook PCs
• Embedded systems
• Telecommunications equipment
• LCD projectors

Procurement Notes

Verify the specific ordering suffix ARQZ corresponds to the 16-lead QSOP package and Pb-Free status as documented in the official datasheet. Confirm that the REEL7 designation matches the required tape and reel packaging format for automated assembly processes before finalizing procurement orders.

Selection Notes

Select this component when system design requires precise thermal management for microprocessor-based environments. Ensure the application utilizes compatible SMBus masters and that the physical layout accommodates the 16-lead QSOP footprint. Verify that the operating voltage range aligns with the system's power supply rails.

Part Context

This part belongs to the ADM1034 family of thermal management devices designed for active cooling control. It serves as a dedicated solution for monitoring thermal conditions and regulating fan speeds in computing and communication hardware where reliable heat dissipation is critical for system stability.

Replacement Considerations

Check for direct pin-compatible alternatives within the same manufacturer's portfolio that maintain identical SMBus protocols and package dimensions. Ensure any substitute supports the required remote diode sensing capabilities and fan drive configurations.
