Talking about the short circuit protection of mobile power
The short circuit protection of the mobile power supply means that when a short circuit occurs when the mobile power supply is output, the power supply will automatically disconnect and stop working. Strictly speaking, the short circuit protection of the mobile power supply is also a kind of over-retention protection. When it reaches the set peak value, it will automatically stop working and play a protective role.
The mobile power supply produced by the power bank factory generally uses two kinds of protection, one is the IC short-circuit protection of the battery itself, and the other is the software board through the MCU to control the input and output of the power supply to achieve short-circuit protection. Some hardware board power supplies Only the IC of the lithium battery can be used for short-circuit protection. In this case, after a short-circuit occurs, it needs to be activated to resume normal use. The activation method is very simple, which is to recharge and activate mobile power with a charger. For the software board, The mobile power supply generally has dual protection. When a short circuit occurs, the MCU will first make a judgment and send a protection signal. Under special conditions, the lithium battery protection IC will also provide protection. After this mobile power supply has short-circuited protection, Generally, it can return to normal as long as you remove the short-circuit load or press the button once, and it is more convenient to use it without recharging to activate.
