The short-circuit protection of mobile power supply is that when the mobile power supply output occurs a short circuit, the power supply automatically disconnects and stops working. Strictly speaking, the short-circuit protection of mobile power supply is also a kind of over retention protection. Its principle is that when the current reaches the set peak value, it starts to automatically stop working and plays a protective role.
The mobile power supply produced by the mobile power plant generally adopts two types of protection, one is the IC short-circuit protection of the battery itself, the other is the software board controls the input and output of the power supply through MCU to realize the short-circuit protection, and the power supply of some hardware boards can only use the IC of the lithium battery for the short-circuit protection, in this case, after the short-circuit occurs, it needs to be activated to restore the normal operation The method of activation is very simple. It is to use a charger to recharge and activate the mobile power supply. For the mobile power supply of the software board, there is generally a dual medium protection. When there is a short circuit, the MCU first makes a judgment and sends a protection signal. Under special conditions, the lithium protection IC will also make a protection. After the short circuit protection of the mobile power supply occurs, the short-circuit load is generally removed Or press the key once to return to normal, no need to recharge to activate, it is more convenient to use.
