Hi, guys!
Knowing how many battery management chips nordic has, I am curious, whether the simple thing as “measuring the voltage of the ordinary AA battery powering the nrf52840“ could be efficiently and solely handled by the chip itself.
The most popular way is of course using the MOSFET + the voltage divider, and just from time to time allowing the voltage to slip into the analog input to measure it against an internal voltage to understand how good is the battery. But is it something which can be solely handled by nrf52840? There probably are some internal circuits for that or am I dreaming?
