Chapter 1

Fast development of telecommunications and networks has accelerated growth of products with hot-plug capability to ensure that systems are always on. Many hot-swap or hot-plug devices are already available in the worldwide market. However, most such devices are for low-voltage applications, whereas 48-V is a standard voltage in most communication systems. The TPS23xx series of hot-swap controllers are principally designed for low voltage applications, but can also be used in very high voltage systems if appropriately designed.

The TPS2330 is a Texas Instruments hot-swap controller that eliminates high- frequency hot-plug or hot-removal transients, reduces inrush current, and pro- vides overcurrent protection. To demonstrate this hot-swap controllability at high-voltage systems, an evaluation module has been developed, as present- ed in this user’s guide. The evaluation module (EVM) can help designers eval- uate the hot-swap controller and simulate hot-insertion and hot-removal ac- tions under varied conditions.

Users will need a 48-V dc voltage supply to test the operation of the EVM.

TPS2330 specifications

Texas Instruments (TI) has established itself as a leader in developing advanced power management solutions. Among its array of products, the TPS2330 stands out as a highly efficient power-path controller designed for various applications, including telecommunications, networking, and embedded systems. This device is a popular choice for engineers seeking an effective way to manage power availability from primary and backup sources.

One of the defining features of the TPS2330 is its dual input control. The controller is designed to manage two independent power sources, providing a seamless transition between them. This capability is critical in applications where reliability is paramount, as it allows for a primary power source (like an adapter) to be complemented by a secondary source (like a battery). The TPS2330 ensures that the load is always powered, even if the primary source fails, allowing for uninterrupted operation.

The TPS2330 also incorporates a sophisticated power-path management technology, which optimizes the flow of power to the load while minimizing losses. This technology enables efficient use of the connected power sources, ensuring that the highest priority source is utilized while maintaining flexibility. The device supports hot-swappable inputs, meaning users can connect or disconnect power sources without interrupting the operation of the circuit.

Another significant characteristic of the TPS2330 is its low quiescent current, which is essential for battery-powered applications. The device's efficiency minimizes power consumption during standby mode, extending battery life significantly. This feature is particularly valuable in IoT devices and portable electronics where power conservation is crucial.

Furthermore, the TPS2330 is built with a robust set of protections to enhance reliability. It has built-in overvoltage, undervoltage, and overcurrent protection, which safeguard connected devices from potential damage. These features are vital for preventing failures in critical applications, helping designers build more resilient systems.

In terms of ease of use, the TPS2330 has a simple design with straightforward external component requirements. This simplicity reduces development time, allowing engineers to quickly integrate the controller into their designs. The device also comes with a wide operating voltage range, making it versatile enough to meet various application needs.

Ultimately, Texas Instruments' TPS2330 is a powerful solution for managing dual power sources with reliability, efficiency, and protection once considered essential in modern electronic design. Its innovative features and technologies make it a go-to choice for engineers looking to enhance their power management designs effectively.
