Dear Johny,the lenght of LIN and HIN trace does not matter so much. Those signals could be affected mainly if traces runs above/below OUT traces running on other layers. A second reason could be a very noisy GND plane due to porely routed power trace...
To properly turn on high side MOSFET (the one drive by HIN), the bootstrap capacitor (the one between BOOT and OUT, supplying the floating structure) shall be charged first.To charge the capacitor thru the integrated bootstrap diode, a low resistance...

Dear Johny, there is no significant capacitance between the two half bridges due to package.Based on the info, the application seems using a shunt resistor for overcurrent.If the GND-shunt-SENSE path is long (inductive), one half bridge could influen...
The high side MOSFET (the one driven by the HVG signal, in the datasheet block diagram) can be turned on only if the bootstrap capacitor (the one between BOOT and OUT) is charged.If HIN if kept high indefinitely, the bootstrap capacitor get dischar...
