PMIC - Hot Swap Controllers are electrical controls used to reduce the risk of damage that can sometimes occur when hot-swapping devices. Hot-swapping is the process of replacing a device or component within a computer system that is already powered on, usually at a lower level than software. A hot swap controller works to safely disconnect and reconnect power between the device and the rest of the computer system, such that the system does not crash or become unstable due to the power sag or surge caused by the insertion or removal of components.

One of the most common PMICs in this category is the TPS2480PWR. TPS2480PWR is a low-cost, low-voltage hot swap controller that enables hot plugging of non-isolated loads which is ideal for minimizing power supply stress during hot-swapping of pluggable application modules. It works by limiting the inrush current of both power-up and power-down events. This protects voltage rails on both sides of the load during hot-swapping operations, ultimately providing a more reliable connection.

The TPS2480PWR is capable of controlling most load types with a large scope of input and output voltages, making it suitable for various applications such as servers, storage systems, communication systems, medical systems and industrial control devices. The device features logic pins for sequencing and allows for easy electrical connection between the load powers and the system. It has a wide operating temperature range from -40 to +125℃ which is suitable for most operating conditions.

In terms of performance, the TPS2480PWR can support a wide range of input voltages from 4.75V to 18V and an adjustable output voltage range from 0.8V to 14V. It provides hot-swap protection for up to 8A of load current, making it suitable for high-power applications. Additionally, the device implements automatic remote sensing and current-limiting circuitry to preventload currents from exceeding the specified current limit while providing a reliable connection between the load and the system.

In summary, the TPS2480PWR is an ideal solution for hot-swapping applications, as it enables a seamless transition between modules while limiting power surges and drops that could damage system components. Its wide input and output voltage range and high current support make it suitable for a variety of systems, with a high level of reliability and safety.
