DRV8601: Working with 1.8V MCU

Hi Arthur,

Understood.  

Let me update the schematic for next board spin and provide here for review.

Hi Arthur,

I am also thinking I can use 8.2.2?

It seems the level shifter provides an isolation between the MCU and the DRV.

But I understand 8.2.2 needs a regulated supply.  VSYS is somewhat regulated (by the battery charger) but not as much as a typical voltage regulator.

Btw attached is the motor we are using.  Also attached is the entire schematic

Would you be able to provide the values for Rs and Cs?

Should I just use Table 6 or 8 depending on 8.2.2. or 8.2.3.

Regards,

Andrew

Hi Arthru,

Can you take a look at the following?

I was assuming the gain should be 2 because Vpwm = 1.8 and VDD btw 3.6 and 4.1.
