Operating voltage range of the nRF5340.

[Maya.]

Hi,

I have a question regarding the operating voltage range of the nRF5340. I found that it can operate between 1.7 and 5.5 volts. However, can we restrict the minimum voltage to 2.7V?
The peripherals we use in our device behave abnormally below this threshold, which is causing issues during the device initialization.
If it is possible, how can we set this minimum voltage range?

Thank you.

Hello,

The nRF53 will still be able to run below 2.7V, but I guess what you are asking is if it is possible to shut down operation at 2.7V?

As I see it you have two options. Either you need a voltage regulator that will keep the voltage above 2.7V, until the battery is empty, or you can use the LPCOMP to let the nRF53 know when the input voltage is below 2.7V, and stop operation (enter system off mode?) after this.

Best regards,

Edvin
