BQ25713B: How to stop charging of BQ25713

Part Number: BQ25713B
Other Parts Discussed in Thread: BQ25713

Hi,

I am NOT using  fuel gauge in my design along with BQ25713B .

Let me know how to stop charging of  BQ25713B once battery is full. 

1. Is BQ25713 can automatically STOP charging by itself ? 

2. If  not able to stop by itself ,  Is there any way to measure real time battery charging flowing into battery ? so that I can stop charger when current goes below certain limit  ( for example less than  200mA ) ?

Regards

    Hi PSG_4,

    1. No, BQ25713 cannot stop charging by itself and requires host processing at all times.

    From the datasheet:

    "According to battery capacity, the host programs appropriate charge current to ChargeCurrent(), or REG0x03/02(). When battery is full or battery is not in good condition to charge, host terminates charge by setting REG0x00[0] to 1, or setting ChargeCurrent() to zero."


    2. The ADCIBAT() register can be used to monitor charge current. I would also recommend monitoring the battery voltage using ADCVSYSVBAT() register.

    Thanks and I hope this helps,

    Peng

    Hi ,  

    Is ADCIBAT() register is monitoring real time battery  charge current  or battery discharge current ? 

    I need to check real time battery charging current. . Please confirm  .
