PMIC - Thermal Management devices form a major part of modern electronic architecture. Thermal management devices not only help in the control and regulation of temperature in PCBs but also facilitate long-term operational efficiency of electronic systems. The ADT7490ARQZ-REEL is one such device that has been designed to create an efficient thermal management system. Let’s take a detailed look at the application fields and working principles of the ADT7490ARQZ-REEL.

Application Fields

The ADT7490ARQZ-REEL is utilized in most modern electronic systems. Being a highly-integrated device, its primary application field is in the control of the thermal management of PCBs in mobile phones and tablets, which require precision and fast response thermal management. In addition, the ADT7490ARQZ-REEL is suitable for thermal management in automotive infotainment applications like GPS units, VR systems, and other computing platforms that require highly accurate temperature monitoring and control. Furthermore, the ADT7490ARQZ-REEL is perfect for temperature management of multimedia systems, entertainment equipment, and other devices that must maintain a safe temperature range.

Working Principles

The ADT7490ARQZ-REEL is a highly advanced thermal management device that has been designed to provide fast response and accurate temperature control. The integrated solution of the device comprises a main controller, one-wire temperature sensor interface, external NTC resistor, over-temperature warning comparator, fan driver module, and PWM controller for external fans. Integrated as one whole thermal management solution, the device provides control over the external NTC resistor and the one-wire temperature sensor. Furthermore, the device’s fan driver module provides adequate power and control signal to an external fan in order to accelerate air flow and reduce temperature inside the system. The high gain of the device ensures fast and accurate temperature monitoring and control.

The ADT7490ARQZ-REEL provides a wide operating temperature range from -40°C to +105°C. This makes it suitable for controlling the temperature in a variety of application areas such as automotive infotainment systems, multimedia systems, and more. Additionally, the device can monitor up to 8 one-wire temperature sensors, ensuring a comprehensive thermal management solution. Furthermore, the device is capable of setting various fan speeds and also supports multiple fan types - PBA/FKN, FFB/FFV, PWM/PFA, PFE, and PWM/PFC. The device can also detect and indicate over-temperature warning via the integrated over-temperature warning comparator.

Once an over-temperature warning is triggered, the device can adjust the fan speed or initiate a system reset thanks to its over-temperature lock and system reset functions. This ensures that the system temperature remains within the safe range, thus avoiding potential thermal-related damage. Moreover, the ADT7490ARQZ-REEL also features a power-saving mode that allows the device to enter a low-power state when the temperature is lower than a certain set point. This helps in maximizing the battery life of the device and preserving energy.

Conclusion

In conclusion, the ADT7490ARQZ-REEL is an ideal device for obtaining a robust thermal management system. It features multiple integrated components for providing accurate monitoring and control of the temperature in systems, such as mobile phones, tablets, automotive infotainment systems, multimedia systems, and other devices. The device can quickly detect any over-temperature warning and take necessary actions. Additionally, it can detect and indicate over-temperature warnings and provide multiple fan control support and system reset options. Its wide operating temperature range and power-saving modes also increase its versatility and efficiency.
