|Title:||BATTERY PACK CHARGE CONTROL DEVICE AND METHOD|
The present invention relates to a battery pack charge control device, and a battery pack charge control device for waking up an MCU operating in a sleep mode in a constant voltage charging state of a battery pack can comprise an AFE for controlling an overvoltage protection level value to be changed to a value higher than a current value before the MCU operates in the sleep mode, and controlling an overvoltage protection trip signal to be generated and transmitted to the MCU operating in the sleep mode so as to wake up the MCU operating in the sleep mode when an increasing voltage value of the battery pack connected to an external charger has a value greater than or equal to the changed overvoltage protection level value.
