1. How does a PMIC hot-swap controller work?
A hot-swap controller protects system components by limiting inrush current during insertion. It monitors parameters such as current and voltage and triggers protection mechanisms such as overcurrent protection or disconnection of power when they exceed the safe range.
-
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. How do hot-swap controllers prevent inrush current?
Through internal current limiting circuits, hot-swap controllers control the rate of current increase at the moment of insertion to avoid damage to the system due to instantaneous inrush current. At the same time, the settable soft start function helps to load the voltage smoothly.
