When the cell voltage is between 2.5V and 4.3V, the first and third pins of DW01 output high levels (equal to the supply voltage), and the second pin voltage is 0V.
At this time, the voltage of the first and third pins of DW01 will be added to the fifth and fourth pins of 8205A respectively, and the two electronic switches in 8205A are in the on-state because their G poles are connected to the voltage from DW01, that is, the two electronic switches are in the on state.
At this time, the negative electrode of the battery cell is directly connected to the P-end of the protection plate, and the protection plate has a voltage output.
