(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.</P> Fri, 05 May 2023 20:01:43 GMT https://community.nxp.com/t5/Power-Management/MC33810-Terminating-Unused-Feedback-Pins/m-p/1645720#M2597 deckhardt 2023-05-05T20:01:43Z https://community.nxp.com/t5/Power-Management/MC33810-Terminating-Unused-Feedback-Pins/m-p/1647328#M2602 <P>Hello David,</P> <P>Yes, all these pins if unused should be terminated to ground.</P> <P>Best regards,</P> <P>Tomas</P> Tue, 09 May 2023 18:04:46 GMT https://community.nxp.com/t5/Power-Management/MC33810-Terminating-Unused-Feedback-Pins/m-p/1647328#M2602 TomasVaverka 2023-05-09T18:04:46Z
