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 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.
-
3. 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.
-
4. How to test the performance of hot-swap controllers?
Performance tests can include plug-in tests, current limiting tests, protection function verification, and current surge measurements. Using an oscilloscope to observe the current and voltage changes at the moment of plug-in is an effective way to verify its performance.
