Part Number: LM5088

Hi Team,

I received the following request from a customer I'm following.

################################################################

Can LM5088 drive a n-channel mosfet with the following characteristics?

    Fabio,
    From the datasheet, the LM5088 high-side gate drive outputs a max voltage of VCC. The internal VCC regulator is typically 7.8V.

    The 5088 can use an external VCC up to 13V, which would definitely turn on that FET.

    Im an not sure the exact turn on threshold of that FET, but if it's 10V the 5088 cannot do it without an external VCC.

    Hope that helps,
    -Orlando
