... This condition is called the power-down status. The power-down status is released when a charger is connected and the voltage difference between the VM and VDD pins is over-current detection voltage 2 or higher. Moreover, when all the battery voltages become over-discharge detection voltage (VDL1,2) or higher, the discharging FET turns on and returns to the normal status. Rev. 1.0 FS3332 14/23 ...
