Part Number:BQ24090
hi Engineer:
My circuit diagram is shown in the figure above.
USB plug in to charge the battery.Testing 5V current is only 20mA.The battery is charging at a very slow rate.The current battery voltage is 3.8V.
ISET2 is connected to BATT through 10K resistor. The current is about 20mA.
Is this normal?Or is there any problem with my circuit?
Thanks！！！
