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. 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. Can the current limit value of the hot-swap controller be adjusted?
Yes, many hot-swap controllers allow users to adjust the current limit value through external resistors or programming interfaces to adapt to different load requirements and circuit conditions.
-
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.
