1. 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.
-
2. 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.
-
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. 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.
