Is PFC necessary in IMC302AF064XUMA1?

[cw2611]

Hey!

I am designing a 48V/8A BLDC motor controller. I have left the PFC pins (PIN44, PIN43, PIN12, PIN21, PIN22, PIN20, PIN19) unconnected since I am powering the controller from a battery pack. While programming using the MCE wizard, there are questions relating to PFC. What should I be doing here?

Hi @cw2611,

If PFC is not being used you can disable PFC by writing bit[0] of FeatureID_selectH  to 0 in parameter .txt file to 

If PFC is disabled  then PFC pins can be left open

Thanks,
