For the undervoltage situations it says switching is stopped for PFC and HBC part. But what is stopped means exactly? Does it connect that pins to the ground or applies some negative voltage or what ? I couldn see any clarification about this topic in both documents and would be happy if you enlighten me.&nbsp;&nbsp;I am looking for a value something like V(OLS) : UVLO saturation. Which gives the voltage value of the gate input when there is an undervoltage<BR /><BR />Thanks</SPAN></P><P><LI-PRODUCT title="TEA1716T" id="TEA1716T"></LI-PRODUCT>&nbsp;</P><P>&nbsp;</P> Thu, 22 Aug 2024 07:46:14 GMT https://community.nxp.com/t5/Power-Management/TEA1716T-Undervoltage-Case/m-p/1938187#M3692 kmesne 2024-08-22T07:46:14Z https://community.nxp.com/t5/Power-Management/TEA1716T-Undervoltage-Case/m-p/1938384#M3693 <P>Hello Heldwein,</P> <P>I think the attached Application Brief provides most answers.</P> <P>The basic state after “stopping switching” is that:<BR />GATEPFC is kept active low (0V).<BR />GATELS is kept active high (prepared for a possible new start condition) (10Vtyp).<BR />GATEHS is kept active low (0V).</P> <P>BRs, Tomas</P> Thu, 22 Aug 2024 10:29:24 GMT https://community.nxp.com/t5/Power-Management/TEA1716T-Undervoltage-Case/m-p/1938384#M3693 TomasVaverka 2024-08-22T10:29:24Z
