Hello,

Please check the datasheet, these pins are the hardware control pins. You will need to select the correct MODE, IDRIVE, and VDS for your application. If you need help, you can copy the EVM, the design files are available here: http://www.ti.com/lit/zip/slvc763

The EVM can be viewed and ordered here: http://www.ti.com/tool/DRV8350H-EVM

Pin 32 is no-connect.

Thank you for answering my question.

but I still have a question .

In the DRV8350H-EVM, the peak output current is 20A，but I need a almost 30A peak current output ,

do Ti have the similar design?

Hello,

The EVM is for evaluation only and not to be used as a final product. The reason the EVM is limited is because the PCB is not designed for very high current operation. Please design your own board if you need more current.
