DRV8302: Could you tell me about ”DRV8302 without using the buck regulator"?

Part Number: DRV8302
Other Parts Discussed in Thread: TPS54160

Hi, team.

I have a question, after seeing the following thread.

e2e.ti.com/.../440369

My customer also wants to avoid using Buck Converter with DRV8302.

So question.

Q:There are comments below in the past submission thread, but aren't there any danger of causing latch-up etc?

> If you prefer the DRV 8302 you can simply leave all pins to the buck regulator unconnected.

> RT_CLK, COMP, VSENSE, PWRGD, PH, PH, BST_BK, PVDD 2, PVDD 2, EN_BUCK, and SS_TR = No Connect.

Best regards,
