Gate Drive Voltage Options
Intersil provides various gate drive voltage options in
ISL6622 product family, as shown in Table 2.
The ISL6622 can drop the low-side MOSFET’s gate drive
voltage when operating in DEM, while the high-side FET’s
gate drive voltage of the DFN package can be connected to
VCC or LVCC.
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.
