MQC883 Series

The MQC883 Series is 2-Series cell Li-ion/Li Polymer battery protection IC. The IC also monitors an abnormal temperature using external thermistor to protect battery pack and system. The IC integrates the battery voltage sensing terminal to be connected to system side, so that battery cells can be monitored accurately without depending on an impedance of protection circuit. This feature provides safer fast charging control.
