The threshold voltage is specified in the datasheet, Table 8:</P> <P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Capture.JPG" style="width: 674px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/206694i6009D353506CB71B/image-size/large?v=v2&amp;px=999" role="button" title="Capture.JPG" alt="Capture.JPG" /><span class="lia-inline-image-caption" onclick="event.preventDefault();">Capture.JPG</span></span></P> <P>For more information, please take a closer look at the <A href="https://www.nxp.com/docs/en/supporting-information/AH1014.pdf" target="_self">AH1014</A>, Chapter 6.4 (Wake via pin WAKE).</P> <P>Best regards,</P> <P>Tomas</P> Tue, 10 Jan 2023 12:22:30 GMT https://community.nxp.com/t5/Other-NXP-Products/tja1043-wake-up/m-p/1580052#M16353 TomasVaverka 2023-01-10T12:22:30Z
