TPS2592ALDRCR: Application Field and Working Principle

Introduction

TPS2592ALDRCR is a Hot Swap controller based on Texas Instruments\' (TI) integrated circuit (IC). Its primary function is to provide efficient and safe protection against overvoltage in High-Value and High-Density Networking systems. TPS2592ALDRCR is used in applications such as next generation servers, cloud storage systems, artificial intelligence (AI) platforms, high-end network switches, and other high-value, high density systems. It also provides ripple protection for voltage regulation (VR) systems and overcurrent protection.

Application Field

The TPS2592ALDRCR is a powerful Hot Swap controller that can protect systems with high value, high density integrated circuits (IC). It can be used in a wide range of applications, including next-generation servers, cloud storage systems, AI platforms, high-end network switches and more. It has a wide input voltage range of 4.5V to 14V, making it suitable for a variety of systems. It also has a low current consumption of only 10.5 mA, making it highly efficient and power-saving.

Working Principle

The TPS2592ALDRCR has several key components which allow it to act as a Hot Swap controller and provide voltage and current protection. It has an overvoltage protection (OVP) comparator, a current monitor and limiter (CML), a fault timer and two pass transistors which provide power to the system. The OVP comparator monitors the output voltage of the system and when it is above the overvoltage limit, the comparator triggers the two pass transistors which shut off power to the system, thus providing effective protection against overvoltage. The two pass transistors also act as switches, allowing the system to be powered.The CML monitors the current flowing in the system and compares the input voltage to the required voltage rating of the system. If the voltage is too low, it shuts off the pass transistors and the system will receive no power. The fault timer monitors the output of the CML and if there is an excessively high current draw, it will shut off the pass transistors as well.

Conclusion

The TPS2592ALDRCR is a powerful Hot Swap controller that can provide efficient and safe protection against overvoltage and overcurrent for high value, high density systems. It has a wide input voltage range of 4.5V to 14V, making it suitable for many applications. It also has a low current consumption of only 10.5 mA, making it highly efficient and power-saving.
