Hi 

This is an isolated gate driver. It is designed for high-voltage half-bridges where a non-isolated half-bridge driver will be damaged. It still requires a high-side power supply, such as a bootstrap diode and capacitor or an isolated DC-DC converter. I do not see these in your layout. Decoupling capacitors C12 and C11 look to be unconnected to a voltage source. Do you have a schematic for this design?

Also, you have routed traces under the device. This will reduce the input to output creepage and clearance rating, and result in a lower voltage isolation of the design.

Hopefully we can resolve the issue and get the gate driver working!

Best regards,

LInks
