BQ25892: How to disable charging via register map

Part Number: BQ25892

Tool/software:

Hello support team, 

My question is basic. I am using the BQ25892. Can I write to one of the registers and turn off charging? I would like to be able to turn the charger off and on. I believe the ICH bits in register REG04 would do that.

Thank you

  • Hi Rez, 

    Yes there are multiple ways to disable charge via registers on BQ25892.

    -As you mention 1 option is to set ICHG in REG04 = 0A (i.e. 0H).

    -Another is to set CHG_CONFIG = 0 (REG03[4]).

    -Finally if you wish to turn off the entire buck converter beyond just turning off charge you can set EN_HIZ = 1 (REG00[7]).

    Best Regards,

    Garrett
