nPM1300 current and voltage measurements capabilities

[AvihayZ]

Hello Nordic team,

I would like to learn more about the capabilities of the nPM1300 in terms of current and voltage measurement. Specifically, I have a few inquiries:

• Could you please provide information regarding the minimum battery current that the nPM1300 can measure through the VBAT pin, along with details on the accuracy of this measurement?

• Is it feasible to schedule current measurements with the nPM1300? Additionally, can measurement data be retrieved upon request?

• Is it possible to measure current through other pins, such as the outputs of the Buck regulators or LDO regulators. If so, I'd appreciate insights into the accuracy of such measurements.

• Can the output voltage of the Buck regulators and LDO regulators be measured using the nPM1300?

• Regarding the last question - 
  • I saw in the datasheet the BUCK1VOUTSTATUS / BUCK2VOUTSTATUS registers which let the software read the Vout value in case its driven by the FSM. Please elaborate what is the format and accuracy of this value.
  • I'm interested in understanding the functionality of the LDSWSTATUS (Load Switch Status) register. Does it contain data related to the voltage/current of the LDO outputs? If so, could you please elaborate on this?

Thank you in advance for your time and assistance,

Avihay
