BQ25890: Way to set hard current limit from BAT to SYS

Dav01

Part Number: BQ25890

Trying to find a way to limit the max current drawn from the battery to the SYStem output.

maybe haven't looked enought in the datasheet, but please help comment if there is a register I missed..
also open to switch charger part-no to one that has a variable current limit (preferabley down to 100mA) from the BATTERY or seen TO SYS

Thx

Hi,

The battery discharge current limit is not adjustable.

Thanks,

Ning.

can you please recommend other chargers that have i2c, and ways to control either VBAT_OUT_CURRENTLIMIT or SYS_OUT_CURRENTLIMIT
