Gate driver output. The output stage is able to drive the power MOSFET's and IGBT's gate.
VCC

Supply voltage of the IC.
Internal UVLO logic prevents the operation at voltages that are insufficient for the efficient gate
driving or signal processing. Both a bulk capacitor (typically around 10 µF) and a high frequency
filter capacitor (100 nF ceramic, mounted as close as possible to the device) are connected between
this pin and GND. An internal clamp structure prevents accidental low energy spikes damaging the
device. An external clamping device should be used to avoid the voltage applied to the VCC pin to
overcome the AMR.
