nRF9160 behaviour between 2.0 V and 3.0 Vhttps://devzone.nordicsemi.com/f/nordic-q-a/82933/nrf9160-behaviour-between-2-0-v-and-3-0-vI am currently designing a PCB which incorporates the nRF9160, and I would like to know the devices behaviour in between 2.0 V and 3.0 V, as this is below the minimum VDD voltage but above the brownout reset voltage. My design will not have a user interfaceen-USTelligent Community 13Mon, 20 Dec 2021 12:35:06 GMTRE: nRF9160 behaviour between 2.0 V and 3.0 Vhttps://devzone.nordicsemi.com/thread/344352?ContentTypeID=1Mon, 20 Dec 2021 12:35:06 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a7ef1094-363f-4883-ba68-fae98c923a63dejans<p>Hi,</p> <p>The recommended operating conditions for nRF9160 determine minimum battery voltage VDD to be 3 V. In revision 1, nRF9160 chip worked with voltages below 3 V, but in revision 2 the chip is not operating below 3 V.</p> <p>It is still possible to use AT commands&nbsp; to put device to flight mode (AT+CFUN=4, AT+CFUN?) as well as to set (and possibly read) the battery status (%XVBAT, %XVBATLVL, %XVBATLOWLVL, %XVBATLOWLVL?).</p> <p>Best regards,</p> <p>Dejan</p><div style="clear:both;"></div>
