DRV8320: the different voltage between VM and VDRAIN

K.Hamamoto

Part Number: DRV8320

I had asked similar question at the following post before.
We had talked with our customer about it . They gave us the detail condition.
Please let me ask again.

https://e2e.ti.com/support/applications/motor_drivers/f/38/p/698016/2576694#2576694

At VM is 42V condition,
Does this device operate if VM - VDRAIN is more than 6V?
Does this device damage If VM - VDRAIN is more than 28V?

Hi Hamamoto-san,

Would you please provide a schematic of how VM and VDRAIN are connected to the device and the FETs?

Hi Rick-san,

I am sorry for the delay in my response.

I appreciate you kind support. However the customer is now very busy. So that , it will take some more time to get the information.
You can close this post at this time. If I got the information, I will post the question again.
