    Understanding power protection circuit in Raspberry Pi

    The attached schematic is taken from the Raspberry Pi drawing. I am trying to understand how it works and I am pretty much stuck with it. I guess the purpose of the resettable PTC fuse and the TVS diode is clear, being as overvoltage protection. It looks quite obvious that the transistors are...
