BQ25790EVM: ADC IBAT readings

Olegas Parmionovas

Part Number: BQ25790EVM

Hi,

Exploring BQ25790EVK connected via USB_TO_ANY and associated Cloud GUI.

ADC IBAT current reading shows charge current, but I can't see discharge current readings, it shows 0.0 A.

Is there any chance to get hold of this value? Any setting, which I didn't enable or it doesn't measure discharge current?

Hope hear from you

    Hello Olegas,

    Please confirm that the EN_IBAT bit is set to 1 (Register 14 Bit 5).

    Charge current will be positive and Discharge current will be negative (2's complement).

    Also, have you confirmed the battery is actually discharging when trying to make this measurement?

    Thanks,

    Khalid
