BQ25703A: bq25703A / VACP and VBAT monitor accuracy

Part Number: BQ25703A

Hi,

Please let me ask about the accuracy of VACP and VBAT accuracy to estimate the worst case of VPSYS. I know that input current and charge and discharge current monitor accuracy is specified in electrical characteristics, so I'd like to know VACP and VBAT monitor accuracy.

Best Regards,

I just come back today.
We don't have ACP and BAT monitor accuracy data. But, ACP, BAT voltage sensing accuracy should be much accurate than IIN and IBAT accuracy. If you have to estimate them, I would use the VDPM_REG_ACC and VBAT_REG_ACC to estimate the ACP and BAT accuracy.
