Power Management Integrated Circuit (PMIC) is an important component in the development of the electronics market. It plays two roles: firstly, it provides an efficient and reliable way to deliver power to the system, and secondly, it oversees the process of thermal management. As one of the components of PMIC, Hot Swap Controllers can provide protection and efficient operation of the system by controlling the power frequency, current limit and temperature of the system.

TPS2483PWR is a single-channel Hot Swap Controller with an integrated low on resistance (RDS_ON) MOSFET. It is designed to regulate the power delivered to the system by protecting the system from over voltage and over current conditions. It also features additional protection for system under voltage lockout (UVLO) and output short circuit protection (OCP). With a low-voltage drive capability, this controller is suitable for applications using small packages.

TPS2483PWR\'s application field mainly includes server, storage and communication equipment boards. Server and storage devices such as server nodes, solid-state drive (SSD) controllers, RAID controllers and other communication/networking devices are all suitable for the use of this controller. In addition, this controller can also be used in automotive applications such as power line communication (PLC) equipment, Ethernet in-vehicle networks and the Network Expansion Modules.

The working principle of TPS2483PWR can be summarized as follows. When the system voltage is normal, the MOSFET is turned on and the power supply is provided to the load. If the load current exceeds the predefined limit or if the voltage drops below the UVLO threshold, the controller enters protection mode and the MOSFET is turned off. With a low-voltage drive capability, the controller can decrease the overall power consumption and increase the system\'s efficiency.

The TPS2483PWR controller offers a wide range of features and configurations, which give users the flexibility to customize the design according to their specific needs. It provides a high-accuracy voltage and current limit mechanism, a strong protection for under-voltage and over-current conditions, and a low-voltage drive capability for efficient power management. It also features a priority-based output enable pin, which makes it convenient to use.

In addition, the TPS2483PWR controller also provides an external synchronization of the lock-out event to the system. This allows the system to quickly react to an over voltage or over current condition, thus protecting the system from over stress and improving the reliability of power system.

In conclusion, the TPS2483PWR is a single-channel Hot Swap Controller that provides a reliable and efficient way to manage the power delivery to the system while protecting it from over voltage and over current conditions. It is widely used in applications such as servers, storage device controllers and automotive applications. With its high-accuracy voltage and current limit feature, low-voltage drive capability and priority-based output enable pin, it is an ideal choice for a reliable power system.
