    Hi Terry,

    At startup in charge mode, the H version not only does the regular D+/D- detection but also allows the host to control the D+/D- voltage levels, thereby allowing negotiations with even more high voltage adapters. In OTG boost mode, the host can now toggle PFM mode on (for higher efficiency in light load) or off. Also, in OTG boost mode, the user can set the minimum battery voltage down to 2.6V max instead of 2.9V max.
