Hello,

Thanks for your interest in LMG5200. Currently, a bootstrap driver is included in LMG5200, and there is no way you can permanently turn on the high side FET as the boot strap cap needs to be charged periodically due to leakage current. You should be able to have very high duy cycle for the high side, but please monitor your bootstrap cap voltage to make sure it is above the UVLO level.

Thanks and regards,
