    Hi,

    If it is only an overload protection ...

    I generally use the output stage Mosfet RdsON as the shunt ...

    just use a BS170 to connect the Drain to a comparator ONLY when Power mosfet gate powered. ( one 4066 gate could do it too, but ... ???)

    sooooo simple ...

    Alain

    PS ; and like that ???
