In this regard, I have consulted the 'MC33PT2000' and 'KTPT2000FRDM6CUG' technical documents for reference. However, there are certain discrepancies between the two documents that have not resolved my confusion:<BR />1.In the application scenario of 6cylinder3bank, there are six components—'C_MHS1, C_MHS2, C_MLS1, C_MLS2' and 'R_GSHS1, R_GSHS2'—present in the schematic of the kit board that are not found in the 'recommended applications' section of the datasheet. What role do these components play in the circuit? Can they be omitted?<BR />2.The kit board's documentation only describes the driving capabilities of the MC33PT2000. Can we utilize the full functionality of the chip as described using the kit board?<BR />3.If I do not have a fuel pump and the Vboost is generated by another voltage chip, do I still need to draw the schematic for the fuel pump and the DC-DC block, and connect the generated Vboost voltage to the Vboost pin?<BR />Thank you very much for your assistance.<BR />Doublemit<BR />December 21, 2023</P> Thu, 21 Dec 2023 03:57:59 GMT https://community.nxp.com/t5/Power-Management/3-questions-about-MC33PT2000/m-p/1778331#M3202 Doublemint 2023-12-21T03:57:59Z https://community.nxp.com/t5/Power-Management/3-questions-about-MC33PT2000/m-p/1778382#M3203 <P>1:都是DNP 就是没有焊接的意思</P> <P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="guoweisun_0-1703137422000.png" style="width: 400px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/255417i9DFCEAB71D0056E5/image-size/medium?v=v2&amp;px=400" role="button" title="guoweisun_0-1703137422000.png" alt="guoweisun_0-1703137422000.png" /></span></P> <P>2：可以</P> <P>3：用不到的可以不画</P> <P>&nbsp;</P> Thu, 21 Dec 2023 05:51:48 GMT https://community.nxp.com/t5/Power-Management/3-questions-about-MC33PT2000/m-p/1778382#M3203 guoweisun 2023-12-21T05:51:48Z https://community.nxp.com/t5/Power-Management/3-questions-about-MC33PT2000/m-p/1778413#M3204 <P>好的，十分感谢。</P> Thu, 21 Dec 2023 06:32:16 GMT https://community.nxp.com/t5/Power-Management/3-questions-about-MC33PT2000/m-p/1778413#M3204 Doublemint 2023-12-21T06:32:16Z
