DESCRIPTION
Connect this pin to the corresponding upper MOSFET gate. This pin provides the PWM-
controlled gate drive for the upper MOSFET and is monitored for shoot-through
prevention purposes.
This pin provides the bias voltage for the corresponding upper MOSFET drive. Connect
this pin to appropriately chosen external bootstrap capacitor. The internal bootstrap
diode connected to the PVCC_NB pin provides the necessary bootstrap charge.
Connect this pin to the corresponding MOSFET’s gate. This pin provides the PWM-
controlled gate drive for the lower MOSFET. This pin is also monitored by the adaptive
shoot-through protection circuitry to determine when the lower MOSFET has turned off.
The power supply pin for the internal MOSFET driver for the Northbridge controller.
Connect this pin to any voltage from +5V to +12V depending on the desired MOSFET
gate-drive level. Decouple this pin with a quality 1.0μF ceramic capacitor.
GND is the bias and reference ground for the IC. The GND connection for the ISL6323 is
through the thermal pad on the bottom of the package.
