PURPOSE: A package module of a battery protection circuit is provided to enable users to easily integrate and miniaturize the same, and to be easily mounted on a battery pack or a batter can. CONSTITUTION: A package module of a battery protection circuit includes protection circuit areas which plural manual elements, a first inner connection terminal area (A1), a second inner connection terminal area (A4), an external connection terminal area, a protection IC, a first FET chip (A34), and a second FET chip are arranged. The first and second inner connection terminal areas include the first and second inner connection terminals which are connected to a battery can comprising a bare cell. The external connection terminal area is closely located on the first inner connection terminal area, and plural external connection terminals and the manual elements are arranged in the external connection terminal area to form the battery protection circuit. The external connection terminals are exposed to the upper surface, and the first and second inner connection terminals are exposed to the lower surface. |
