Protect the chip to make it work normally. The protection chip works normally: the MOS tube on the protection chip can be turned off at first. After the battery is connected to the protection chip, the MOS tube must be triggered first, so that the P+ and P- terminals can output. tension. The common trigger method is to use a wire so that B- and P- are shorted. In the design process of the lithium battery PACK, the corresponding lithium battery protection board or BMS, and even various communication protocols should be used.
