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. What are the main applications of hot-swap controllers?
Hot-swap controllers are widely used in servers, telecommunications equipment, data centers, power distribution systems, and industrial equipment, where hot-swap requirements are high and stability and safety need to be ensured.
-
3. 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.
-
4. What are the common protection functions of hot-swap controllers?
Typical protection functions include overcurrent protection, short-circuit protection, overvoltage protection, undervoltage lockout, overtemperature protection, etc. These protection functions ensure the safety of equipment under different conditions.
