https://devzone.nordicsemi.com/f/nordic-q-a/79043/nrf52833-dk-questionI have a question regarding the power sequence mentioned in the nRF52833-Dk guide: or the power sources section the guide explains it as: I drew the body diode of U15 as shown. If I put 1.8V on P21, in the beginning of time abouten-USTelligent Community 13Wed, 01 Sep 2021 12:06:26 GMThttps://devzone.nordicsemi.com/thread/327599?ContentTypeID=1Wed, 01 Sep 2021 12:06:26 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7cbcb661-c9e3-4bc8-8629-20164afca9f5ketiljo<p>You&#39;re partly right in your analysis. The diode drop will be far less than 0.7 V when the current draw is low. So the AND gate will have just enough voltage to operate in the few ns before it can fully turn on the switch. I agree that it&#39;s not optimal.</p><div style="clear:both;"></div>
