BQ27541: Only draw power from battery while USB is connected

Part Number: BQ27541

Is it possible to not use power from USB while battery and USB are connected? While USB is connected, I would like the battery to not charge and for power output to be only from the battery, not the USB.

    Hi Jason

    The bq27541 is just a gauge and not a power path controller.The gauge just monitors the charge into and out of the battery and predicts SOC. It doesn't have an AFE to turn on and off the charge and discharge fets

    thanks
