BQ25710: BQ25710 Design Recommendations for Adapter-Only (AC Only) Mode

Part Number: BQ25710

HI Team 

I would like confirm BQ25710 adapter only set recommend from TI ?

When adapter only we need make sure adapter can't trigger adatper OCP. 

1.Which register we should follow to set  ? 

2.When we disable IDPM the charger input current will follow the external current limit right ? 

 

Thanks

Louis Lo

    Input current can be set in either register 0x3F or the external resistor.

    No, The device will need IDPM enable in order for input current regulation.

    You can either set the input current using the 0x3F register, or you can set it using external resistor, either way Indpm needs to be enable for input current limit to be effective.

    You can use REG 0x31[7] to determine if you use the register or the resistor to set limit.
