  • [FAQ] Why do SHx and GHx Float?

    Alicia Rosenberger
    Alicia Rosenberger
    The reason that SHx floats is due to the high-side gate architecture. When the low-side FET is not on, the leakage from SHx will have no path to ground which means that SHx will float up to VM, through the body diode of the FET, as shown in the diagram…
