  • Protection circuit module for a secondary battery and a battery package using same
    Patent number: 7781089
    Abstract: To realize reduction in the size and cost of a protection circuit module for a secondary battery. A protection circuit module 1 for a secondary battery has at least a wiring board 2 having multiple battery-side external terminals 4a and multiple load-side external terminals 20a, and semiconductor components 12 and 14 mounted on the wiring board 2. On the wiring board 2, the battery-side external terminals 4a are disposed on a surface 2a, and the load-side external terminals 20a are disposed on a surface 2b on the opposite side. The semiconductor components 12 and 14 have multiple external connection terminals 12a and 14a arranged on a single plane surface, and are mounted face-down in a bare-chip state on the surface 2a of the wiring board 2.
