Battery monitor for nRF52832

Enrique over 8 years ago

Does nRF52832 have battery monitor?

I can't find in the datasheet if there is an externarl circuit to monitor the battery. I'm using a CR2032 coin cell battery.

Thanks

You can measure Vdd on the chip with the SAADC, Vdd is one of the inputs you can select for any of the channels. So as long as your battery is providing Vdd directly, you can measure it.

That's true, but recently I've been learning more about battery monitoring than I ever wanted to know. Battery voltage does not have a simple relationship to battery usage. If you are drawing a lot of…

Thank you all for your answers, considering what you said and the fact that I'm looking for low cost, I will use the SAADC to measure the Vdd. Since I will measure the remaining battery life every few minutes, I consider there is no need for using an extra IC.

I will try this way and let you know how it went.

Best regards!
