    Battery protection circuit chip ID

    I have a lithion ion battery that has a bad chip in the protection circuit. The number on the chip is 10AH2. There is also a square box with the letters SC in it, probably the manufacturer.

    The chip is 2 layers, black on the top and white on the bottom. About 1/8"x1/4 inch with a surface mount soder connection on each side. There is an "F" on hte pcb next to it, so it could be a fuse. This chip is connected to the source terminal of a N-channel mosfet TPC8026. Tried to get pictures, but it is too small to show anything in focus with my camera.

    I have googled everything posssible with no success. Any help identifying what it is would be greatly appreciated.

        Have searched Digi-key and Mouser and can not find any SCP or thermal fuses that match this. Do you know a source?
