Hi experts,
My customer IS using bq25883, but charging current can't meet their target, they used an usb adapter[ 5v 2A] from their end-customer and the battery is 2s Li-Battery ,8V. BQ25883 can only identify this adapter as unknown device, so the adapter actually output 500mA current. to improve this, my customer try to enable the ICO function and set the REG_0A register to 1000mA, by using multi meter to measure the charging current, they can see the improvement , the charging current increased from 280mA to 420mA, but still far behind their expectation. based on this use case, would you please suggest how to maximize the adapter's capability and increase the charging speed. thanks.
