With the rapid development of electronic technology and the diversification of application fields, the power management (PMIC) solutions and thermal management of chips produced by market enterprises are constantly showing diversified development trends. The "ADT7490ARQZ-R7" is one of the most popular PMIC Thermal Management products available in the market today.The ADT7490ARQZ-R7 is a thermal protection, temperature sense, thermal management, power management and monitoring integrated circuit, which can be used in various types of systems to ensure the stability and reliability of the system running. It is mainly used in computer systems, data storage systems, communication networks and most other types of systems.The main functions of the product are to control the temperature of the system, and accurately measure the temperature of each component or system. This product integrates thermal protection, temperature sensing, thermal management, power management and monitoring functions, providing the system designer with an effective way to control and monitor system temperature.The working principle of this product is based on two integrated circuits: an analog temperature sensor and a protection circuit. The temperature sensor is used to detect the temperature of each component or system in real time, and convert the temperature signal into a voltage signal. The thermal protection circuit stores the pre-set temperature condition, and when the temperature exceeds the set value, it will trigger the power supply control line to control the power supply output of the system and prevent the system from overheating.The main advantages of the ADT7490ARQZ-R7 are the wide temperature range and low power consumption. This product can support temperature ranges from -40°C to +85°C. The power consumption of the complete device is only 1.3W. Thus, it is also a low power consumption device excellent for thermal management and power management.In addition, the ADT7490ARQZ-R7 has excellent accuracy. The temperature sensing accuracy is ±1°C, and the control accuracy is ±2°C. These functions enable precise thermal control and monitoring of the system and therefore improve the system performance and increase its stability.Moreover, the small size and high integration of the ADT7490ARQZ-R7 make it suitable for most application fields. This product comes in a 3.3V, 6-pin package with a dimension of only 3.5mm×2.1mm. Furthermore, it has a low operating voltage and low pin to pin voltage-drop, which makes it easy to integrate into the system.In conclusion, with its excellent performance, small size and low power consumption, the ADT7490ARQZ-R7 is a perfect choice for many application fields, such as computer systems, data storage systems, communication networks, and more. It provides a cost-effective way to control and monitor system temperature, and improve system performance and stability.
