Overview
The ADT7468ARQ is a board-mount thermal controller and voltage monitor manufactured by onsemi, housed in a 24-QSOP package. It features digital output via I2C/SMBus interfaces with an accuracy of +/- 2°C. The device operates within a temperature range of -40°C to +120°C and supports remote sensor configurations for comprehensive system monitoring.
Feature Summary
- Integrates fan control capabilities alongside temperature monitoring functions
- Supports both internal and external sensor topologies for flexible thermal management
- Utilizes standard two-wire I2C and SMBus communication protocols
Applications
- Server and storage system thermal management
- Industrial equipment temperature monitoring
- Telecommunications infrastructure cooling control
Procurement Notes
Verify the manufacturer designation carefully as sources list both Analog Devices and onsemi. Confirm the specific suffix (e.g., ARQZ) against your bill of materials. Check current product status as listings indicate discontinued or limited availability states. Ensure interface compatibility with existing I2C/SMBus controllers before procurement.
Selection Notes
Select this component when integrated fan speed control and multi-zone temperature monitoring are required in a single IC. The 24-QSOP package suits space-constrained designs needing surface mount installation. Verify that the +/- 2°C accuracy meets system thermal safety margins. Ensure the operating voltage range aligns with the target system power rails.
Part Context
This part belongs to the ADT7468 series of hardware monitors designed for complex thermal environments. It combines analog-to-digital conversion with logic control for active cooling elements. The device replaces discrete sensor and fan driver circuits, reducing component count and board complexity in high-density electronic assemblies.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with the official onsemi selection guide for compatible alternatives within the DBCool family.
