LVG

10

Low-side transistor driver. The gate of an N-channel MOSFET or IGBT having an

equivalent gate capacitance lower than 1 nF can be directly connected to this pin.

NC

11

Unconnected pin for creepage purpose

OUT

12

Reference voltage of the floating gate driver. To be connected to the middle point of

the half-bridge.

HVG

13

High-side transistor driver. The gate of an N-channel MOSFET or IGBT having an

equivalent gate capacitance lower than 1 nF can be directly connected to this pin.

BOOT

14

Supply voltage of the floating gate driver. A ceramic bootstrap capacitor must be

placed between this pin and OUT pin
