DRV8305: How to use this device to design a three-phase inverter with DC side voltage greater than 45V?

Part Number:DRV8305

Hello everyone

          I have a question recently.  according to the datasheet of DRV8305，the maximum working voltage is about 45V,  Now I want to design a three-phase inverter with a DC voltage of 70V using this device. How should I design the power system of the DRV8305?

Best regards
