Hi j
Think your IC is a AP4501M which is a dual N and P power mosfet in a single smd package. Datasheets are available on line but cant find a UK supplier. Check out the pin connections on the sheet. Expect this type of device would be short circuit if faulty. Hope the info is of help.
Regards
John.
