Hi, I am trying to to get my HIP4081a gate driver to work with my class d pwm complementary outputs. I am powering the drive with +12 volts and using a 0.47uF and IN5817 for the bootstrapping circuit. When I check the output there is just a noisy sine wave and not a square wave of 0 -10v. Can someone please help me?

No. Not without complete informations.

Show your complete schematic, even hand drawn.
Show your PCB layout.
Show where you conneted the scope tip and GND.
Show all supply voltages and input signals.
