Pin Function
Floating Bootstrap Supply Pin for Upper Gate Driver.
Input PWM Signal for Controlling the Driver.
Output Disable. When low, both UGATE and LGATE are
driven low and the normal operation is disabled.
12V Supply Voltage.
Lower Gate Driver Output. Connected to gate of low side
power N-MOSFET.
Ground. The exposed pad must be soldered to a large
PCB and connected to GND for maximum power
dissipation.
Connect this pin to the source of the high side MOSFET
and the drain of the low side MOSFET.
Upper Gate Driver Output. Connected this pin to gate of
high side power N-MOSFET.
