Other Parts Discussed in Thread: BQ25622
On page 8 of the BQ25620 / BQ25622 datasheet, the following current specifications are given...
IQ_BAT (ADC disabled): 1.5-3uA
IQ_BAT_ADC (ADC enabled): 260uA
I assume this 260uA specification is only meaningful while the ADC is in continuous mode, since one-shot disables the ADC_EN upon completion, this seems clear.
My questions are about how register 0x27 "ADC_Function_Disable_0" affects IQ_BAT_ADC:
1) Is this 260uA specification the quiescent current when all ADC functions are enabled?
2) If only VBAT is enabled, and all other ADC functions are disabled, is the quiescent current reduced?
3) Is there any estimation for how much each ADC function affects IQ_BAT_ADC?
A related question, how does register 0x27 "ADC_Function_Disable_0" affect the temporal resolution of the ADC? With fewer functions enabled, are the readings updated more frequently?
