Overview
The ADT7466ARQZ-REEL is a board-mount thermal controller and voltage monitor manufactured by onsemi, distributed under the Analog Devices portfolio. It features an 8-bit resolution with accuracy ranging from +/- 3°C to +/- 5°C. The device operates within a supply voltage range of 2.7V to 5.5V and supports digital output via 3-Wire, Microwire, or SPI interfaces. It accommodates remote configurations and functions across a temperature range of -40°C to +125°C in a QSOP-16 package.
Feature Summary
- Integrated thermal control and voltage monitoring capabilities
- Supports multiple digital communication protocols including SPI and Microwire
- Capable of remote sensor configuration for external temperature sensing
Applications
- Server and storage system thermal management
- Industrial equipment temperature regulation
- Voltage monitoring in embedded systems
Procurement Notes
Verify the manufacturer designation carefully, as this component is produced by onsemi but often listed under Analog Devices distribution channels. Confirm the specific suffix indicates reel packaging and ensure compatibility with existing SPI or Microwire interface requirements before integration.
Selection Notes
Select this component when both thermal regulation and voltage monitoring are required in a single integrated circuit. Ensure the application environment falls within the specified operating temperature limits and that the host controller supports the selected digital interface protocol for proper data exchange.
Part Context
This part belongs to the ADT7466 series of thermal controllers. While historically associated with Analog Devices, current documentation identifies onsemi as the manufacturer. It serves as a specialized solution for managing heat dissipation and power integrity in compact electronic assemblies requiring precise environmental oversight.
Replacement Considerations
Direct substitutes include ADT7466ARQZ and ADT7466ARQZ-RL7. Verify pinout compatibility and interface protocol support when transitioning between these variants to ensure seamless integration without hardware modifications.
