BATTERY PROTECTION MODULE PACKAGE

摘要

The present invention relates to a battery protection module package. A small battery protection module package according to an embodiment of the present invention comprises: a lead frame on which a plurality of external terminals are formed; a printed circuit board which is arranged to be laminated on the lead frame; a plurality of electrically connected internal terminals, a protective IC, an FET, a resistor, and a capacitor which are arranged on the printed circuit board and electrically connected to each other. The resistor and the capacitor are mounted, by using surface mounting technology, on a pattern of the printed circuit board. The internal terminals are electrically connected to the external terminals. According to the present invention, a battery is efficiently protected from over-discharge, overcharge and over-current of batteries and has a size smaller than a conventional battery protection module package, thereby achieving miniaturization of the battery and reduction in production costs thereof.
