The RC filter needs to be carefully designed in order not to influence the charging time of the bootstrap capacitor CBS.</P><P><span class="lia-inline-image-display-wrapper"><img src="https://community.nxp.com/t5/image/serverpage/image-id/56815i2C9A62DBA4B89BB0/image-size/large?v=v2&amp;px=999" title="Optional RC filter to VBS pin.png" alt="Optional RC filter to VBS pin.png" /></span></P><P><BR />I hope it helps you.</P><P></P><P>Have a great day,<BR />RadekS</P><P></P><P>-----------------------------------------------------------------------------------------------------------------------<BR />Note: If this post answers your question, please click the Correct Answer button.
