MP2723A ADC values when discharging

Battery Management
1

Hi,
I’m using the MP2723A charger.
I noticed that ADC doesn’t seem to work in discharge mode, that is with only the battery connected.
Apparently all values appear to be stuck with the last adc read and just don’t change until I plug the USB and start charging again.

I checked the datasheet and apparently it should be possible to read
Page 26 of the datasheet reads:
In battery discharge mode, the ADC monitors the battery voltage, system voltage, and NTC voltage.

If this is indeed true, should I do something differently when only the battery is connected?

Thanks!

Hi Toni,
Please refer to page 26, ensure the the proper bits are enabled during discharged. You have to toggle the (EN_ADC_DSG) only once.
