 I use the DCDC mode to enhance power consuption. According to Product Specification in release 1.3 (and unlike nRF52840), the product may run down to 1.7V but I noticed that application don&amp;#39;t run</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Tue, 21 Jul 2020 09:38:28 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/63988/nrf52810-won-t-run-under-2-5v" /><item><title>RE: nrf52810 won't run under 2.5V</title><link>https://devzone.nordicsemi.com/thread/260957?ContentTypeID=1</link><pubDate>Tue, 21 Jul 2020 09:38:28 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:f7049377-a1b5-408f-ac45-0eb2d8b21f17</guid><dc:creator>Turbo J</dc:creator><description>[quote userid="92094" url="~/f/nordic-q-a/63988/nrf52810-won-t-run-under-2-5v"]With such a low voltage, I may not program nor debug the product with my J-Link.[/quote]
&lt;p&gt;The J-Link disables sleep during debugging and programming, resulting in &lt;em&gt;much&lt;/em&gt; higher current consumtion (several mA). A CR2032 can support this current (barely) when nearly 100% full, but not when discharged to 2.5 Volts.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;Note that this debug state also needs a power cycle to turn off (and re-enable deep sleep states). I recommend using a current limiting power supply for R&amp;amp;D with NRF chips.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
