The ISL6622A allows the low-side MOSFET(s) to operate
from an externally-provided rail as low as 5V, eliminating the
LDO losses, while the high-side MOSFET’s gate drive
voltage of the DFN package can be connected to VCC or
LVCC.

The ISL6622B sets the low-side MOSFET’s gate drive
voltage at a fixed, programmable LDO level, while the
high-side FETs’ gate drive voltage of the DFN package can
be connected to VCC or LVCC.
