1. What is a PMIC hot-swap controller?
A hot-swap controller is a power management integrated circuit that allows circuit boards or modules to be safely plugged and unplugged while the device is running without causing damage to the device itself or the power system.
-
2. How to choose a suitable hot-swap controller?
When selecting a hot-swap controller, you should consider the system's current and voltage range, protection mechanisms (such as overcurrent protection and thermal shutdown), response time, power dissipation, and other required functions.
-
3. What is the difference between a hot-swap controller and a power switch?
Hot-swap controllers actively manage current and voltage changes during the plug-in process, while ordinary power switches only have simple on-off functions and cannot provide protection and control functions.
-
4. What voltage ranges do PMIC hot-swap controllers support?
Hot-swap controllers support voltage ranges from low voltage (such as 5V) to high voltage (such as 48V or even higher), depending on the model and application scenario of the controller.
