Hi Nordic Team,
Previously, with the nRF52840, we could use the internal ADC channel to directly measure the supply voltage (VCC) for battery monitoring without external components. However, for the new nRF54L15, I haven’t found clear documentation on whether a similar internal ADC channel exists for VCC measurement.
-
Does the nRF54L15 provide an internal ADC input channel to measure the supply voltage (VCC) directly, similar to older Nordic devices?
-
If not, is it necessary to route VCC (or battery voltage) to an external GPIO pin with a voltage divider for ADC measurement?
-
Are there recommended configurations or reference circuits for battery voltage monitoring on the nRF54L15? (low-power coin cell)
Any insights or documentation references would be greatly appreciated!
Thank you!
