The ADM1023ARQZ-REEL7 is a Thermal Management application from Analog Devices. It is from the Advantage Power Management IC (PMIC) series of chassis-level power management ICs designed specifically for critical applications.

This IC serves multiple applications such as monitoring, controlling, and protecting thermal sensitive components within an electronic system. It is also designed to alert users of predefined thermal thresholds in order to prevent device or system damage. The thermal management IC can also be used to effectively manage heat dissipation and airflow for a variety of applications, including server racks, fan speed control, embedded automotive applications, communication systems, large chassis systems and consumer electronics.

The ADM1023ARQZ-REEL7 supports up to seven thermistors which can be monitored and controlled simultaneously. It integrates a temperature sensor and thermal regulator to monitor system temperature across multiple channels, while controlling up to seven independent fan speeds. It is well-suited to help regulate fans, as well as providing over/under temperature/voltage protection, overvoltage/undervoltage protection and thermal shutdown protection.

The device also uses two different types of control logic to monitor thermal management. Open source software libraries are available to provide a graphical user interface for visualizing and setting up the settings for the various parameters. The eight-bit temperature readings from the remote thermal sensing channels can be programmed in order to monitor thermal performance.

The working principle of the ADM1023ARQZ-REEL7 revolves around the temperature sensor, which measures the temperature of the system. The data is then passed on to the thermal regulator, which is responsible for controlling the speed of the fans and other thermal management-related tasks. To prevent the system from overheating, the thermal regulator also has in-built over/under temperature and overvoltage/undervoltage protection that ensures the utmost safety for the system. Furthermore, it can operate at temperatures ranging from -40°C to 125°C.

In sum, the ADM1023ARQZ-REEL7 from Analog Devices is an ideal thermal management solution for critical applications. It combines a temperature sensor and thermal regulator to effectively manage platform temperatures and provide comprehensive thermal protection for a wide range of applications, including servers, communication systems, large chassis systems, and consumer electronics.
