MC33810 - Terminating Unused Feedback Pins

[deckhardt]

I am working with a design where we are using (x4) MC33810 ICs. (x2) MC33810 are fully populated but (x2) MC33810 are used only for driving injectors. I could not find any documentation of if you should terminate the feedback pins (FB0, FB1, FB2, FB3) and RSP, RSN when not in use. Any insight would be greatly appreciated.

Hello David,

Yes, all these pins if unused should be terminated to ground.

Best regards,
