Hi,
I used a gate driver from Fairchild (FAN73832) and connected it the way the datasheet shows (image 1),
and I expected that both outputs high side and low side to range from 0V to 15V.
But when I connected the chip and measured the output, the high side output ges from -5V to 10V.
I expected both outputs to switch between 0V and VCC (which is 15V in my case), did I make a wrong assumption
or is there is a mistake in the way I connected the circuit.
(I attached the oscilloscope images, which are taken between ground and pins 5 and 7 on the device)
