Power management integrated circuits (PMICs) are essential components in modern electronic devices. They are responsible for managing the power supply to various components of the device, ensuring that they receive the correct voltage and current. One important type of PMIC is the hot swap controller, which is used to manage the insertion and removal of components from a live system. In this article, we will discuss the mainstream models of PMIC hot swap controllers.

Hot swap controllers are used to manage the insertion and removal of components from a live system. This is important because it allows components to be added or removed without interrupting the operation of the system. Hot swap controllers typically include features such as overcurrent protection, overvoltage protection, and thermal protection to ensure that the system remains safe and stable during the insertion and removal of components.
