https://devzone.nordicsemi.com/f/nordic-q-a/58975/kiwi-project-rgb-ledHello, Because I have no space for additional transistors on my board I made a design with nrF52840 and rgb led connected to 5V. Configuration o GPIO pins: H0D1 Value=7 High drive &#39;0&#39;, disconnect &#39;1&#39; (normally used for wired-and connections) en-USTelligent Community 13Thu, 19 Mar 2020 15:17:25 GMThttps://devzone.nordicsemi.com/thread/240690?ContentTypeID=1Thu, 19 Mar 2020 15:17:25 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0020bba8-2de9-47a8-a9c5-e955d07eae3dharti<p>Sorry if I open again this topic.</p> <p>What is the protection diode&#39;s current rating?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/239359?ContentTypeID=1Wed, 11 Mar 2020 14:08:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:49a0d4b8-e45c-42fa-aa7f-71d476993a0aharti<p>I thought this :-(</p> <p>Thanks for fast reply.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/239342?ContentTypeID=1Wed, 11 Mar 2020 13:31:16 GMT137ad170-7792-4731-bb38-c0d22fbe4515:44bfaf09-6977-4647-b6c6-6b8836fdfb23Kenneth[quote user=""]If leds are switched off the voltage at the ports P0.19, P0.24, P0.25 are increased over VDD (3.3V) until around 3.6V.[/quote] <p>You are loading the internal ESD diodes in this case (which is why it does not exceed ~3.6V), loading the ESD diodes&nbsp;over time may cause EOS damage. So we can&#39;t recommend you to do this.</p> <p>Best regards,<br />Kenneth</p><div style="clear:both;"></div>
