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. 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. 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.
