BQ25700A: Does the BQ25700A has a Full Gauge Monitor incorporated?

cristian david lopez robayo

Part Number: BQ25700A

I'm designing a complete smart battery charger, i find that the BQ25700A has a lot of useful features for my application. I know from the datasheet, that the IC has a Power/Current Monitor and a Power Path Management, but the cuestion is, with the power monitor do i have a full gauge monitor or i have to use another IC for the task?.

bq25700A itself can report the power going to the system, you do not need an extra IC to achieve that.

Thanks Yipeng for the answer, with the information of the currents ans voltages, how can I get the SOC (state of charge) of the battery?.
I need to know an estimation of the charge remaining in the battery and how much time is left. It is not a fuel gauge monitor task?.

Thanks Yipeng for take time to answer. i really appreciated.

bq25700A doesn't have gauge function to report SOC. It is a charger.
