BQ24703: I want to know if it's charging.

Part Number: BQ24703

Hello~?

When charging the battery using the BQ24703, do you know "charging" or "charging completed"?
For example, does the red LED light up while charging and is there another pin that lights up the blue LED when charging is complete?

Thank you~!

    Jang,
    I check this part's datasheet and it seems it is no charge status LED indicator for customer. So there is no pin to indicate BQ24703 is in charging situation or charging complete situation. But there is IBAT pin can be used ==>IBAT: Battery current differential amplifier output. The output of this pin produces a voltage proportional to the battery charge current. This voltage is suitable for driving an ADC input. You can use MCU to read this pin to judge charger is in charging or not. BTW, could you let me know what is charge specification then maybe I can suggest suitable device for you.
    Thanks
