Hi team, 

I want to check the difference between BQ25890 and BQ25890H,

I have seen the HW differences in https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/686336/bq25890-bq25890-and-bq25890h

I want to double check with you are there any supplements? Are there any differences between these two device FIRMWARE development?

Thanks!

    Hi Kailun, 

    There are not differences in firmware development between the BQ25890 and BQ25890H. 

    To achieve the differences outlined in the thread you linked some of the register map is changed on the BQ25890H compared to the original BQ25890. Registers where 1 or more bits are changed between the devices are REG01, REG03, and REG0A. All other registers are configured the same on both devices. 

    Best Regards,

    Garrett
