PMIC - Hot Swap Controllers are essential for applications such as servers, storage systems and network systems that need to control power circuit to ensure reliability and system-level protection. TPS2330IDRG4 is one device belonging to the family of Hot Swap Controllers applicable for the said applications. This document details about TPS2330IDRG4 application field and working principle.

The TPS2330IDRG4 is an integrated circuit intended for Hot Swap applications. It provides current limiting and thermal fold-back protection for single supply systems, eliminating the need for a gate drive and discrete circuitry. The device supports a single supply at either 5V or 12V and can handle loads up to 2A. The device provides a combination of current-limiting and thermal fold-back protection in a single, robust package. It also has protection features such as user-programmable overcurrent limit with 4-bit OVP limit and foldback voltage clamp.

Should an unprotected load be inserted on a high-voltage bus, application of the TPS2330IDRG4 will protect the load, the supply and the system components. The device is designed to work with 3.2V to 5.5V hot swap applications. It is specifically designed for applications including servers, storage systems and network systems, for which a Hot Swap Controller is absolutely essential. The adjustable current limit and thermal shutdown provide greater system protection and the single-supply operation saves board space.

The TPS2330IDRG4 consists of a power switch, coupled with a programmable current-limit circuit, overvoltage protection, undervoltage protection, and a foldback voltage clamp, all of which are monitored and controlled by a microcontroller. When the load is applied, an internal power switch controls the current sourced from the external supply. A voltage regulator ensures that the internal devices operate at the correct voltage levels. The power switch is the key component which allows current to flow through the system to the load.

The programmable current limit circuit limits the external current to the safe user-programmable level. The device also provides overvoltage and undervoltage protection, which prevent the voltage from exceeding safe levels that could potentially damage the system. The foldback voltage clamp is a handy feature for soft-starting applications, which reduces the voltage seen at the load during start-up.

The TPS2330IDRG4 Hot Swap Controller provides reliable system-level protection, while saving board space and reducing component count. It also offers an adjustable current limit and thermal shutdown, providing greater protection and flexibility. The device can withstand operating temperatures from -55°C to +125°C.

In conclusion, the TPS2330IDRG4 Hot Swap Controller is an essential device for applications such as servers, storage systems and network systems. It has the ability to provide current limiting and thermal fold-back protection in a single, robust, integrated package. Its adjustable current limit and thermal shutdown provide greater system protection and flexibility, making it an ideal choice for cost effective, power efficient Hot Swap applications.
