Part Number: BQ25710

HI  

Customer have some question on other  SMBus address of 0x37 , Could you help to check them .thanks.

1. First, please help confirm whether BQ25710 has an SMBus address of 0x37h?
If so, what parameters does the register at this position represent?
And please help confirm the location of 0x37h bit11 of BQ25710
Is it possible to perform writing action? (Fill in "0" or "1" for 0x37h bit11)

2. Or is it that BQ25710 itself does not have an SMBus address of 0x37h?
If not, then EC places a command of 0x37H bit11 on the CHG IC (fill in "0" or "1")
Is there any problem with this?

    There is no register 37 in the datasheet, but I do see register 37 in Battery Management Studio which has a read-only value for "Lout".

    There should not be any issues writing to this registers, The data will just be ignored.
