    BD8616 circuit

    Anyone came accross BD8616 circuit? It is used in e.g. Fujitsu Lifebook E752
    mainboard Ecp562713-x3
    One pin connects Gate of the first mosfet. I have about 5V only on that Gate .
    Unfortunatelly I did not find a datasheet.
    Your help would be appreciated.Thank you

    I think I have a donor board with this charging IC and working main power rail. I'll try to take a look tomorrow.

    However, if you're dealing with a P-Channel mosfet, 5V might be perfectly fine. Does the 19V pass the MOSFET or it doesn't?

      Thank you for your reply.

      Yes, but I thought that P mosfet should have Gate grounded, that is there should be 0V or not?

      And in case it were P-Channel mosfet, if I use 19V to gate, will the mosfet survive?
