BQ25710: PSYS connection for dual charger

Tamio Yokokura

Part Number: BQ25710

Hi, BQ25710 support team

My customer is developing the system with the dual charger and dual battery pack. I think that PSYS can connect as following picture because PSYS is the output current.

If two PSYS output can't be directly connected to RPSYS, what circuit is needed?

Thanks

Hi Tamio,

Yes, you can tie the PSYS output together. Another option is to read the PSYS ADC value from 0x23 of each charger and add them together.

Thanks and I hope this helps,

Peng

HI, Peng,

Thank you for supporting.

Once, I will try to observe PSYS output when two PSYS output are combined.

Thanks
