The Gate of the right pair of MOSFETs which are responsible for protecting the battery pack from overcharging is connected to the positive terminal of the battery pack. When the battery is overcharged, the DW01 IC will sense the overcharge condition using the internal potential divider circuit and will turn on the OD transistor.
At high temperatures (between 158°F and 212°F, or 70°C and 100°C), thermal runaways can occur, causing a chain reaction that destroys the battery pack. During fast charges, batteries must be cooled down.
