I agree that integrated solutions are better but maybe i find one which has that kind of power fets already in it.

There is no application note but luckily here (http://www.cypress.com/documentation/reference-designs/ccg1-type-c-legacy-usb-device-cable-paddle-card-reference-schematics) is a reference design for download. I am not too sure, though, if that helps.

  ok that link came with adverts attached on gmail so it's here:

 yyyehhhh.... lots of Power P-FETs and N-FETs... about 4 or 5 that i
can count.... not a big fan of that kind of design strategy, i much
prefer the simplicity of integrated solutions, not least that they
save quite a lot of space.

 except of course they have to do _exactly_ what you need...

 thanks julius - was there an app note / reference design around?
