BQ25792: I_BAT and I_BUS readings

Part Number: BQ25792

Hello I want to confirm if it's possible to measure both I_BAT and I_BUS values simultaneously. When I use only the battery, it shows a discharge current, but when I charge the battery externally, I read 0 current on I_BAT. Jeff mentioned that I can't see both current values simultaneously if the load is greater than what the bq can handle. Is my understanding correct? 

  • Hi Azad,

    You should be able to read both currents at the same time.  The charger does not report discharge current while in charge mode (vs OTG mode) unless the IBAT pin register (REG0x14[5]) = 1.  Also, battery current is not current if running average is selected.

    Regards,

    Jeff
