BQ24196: Questions for bq24196 charging current control accuracy

Jacky Wang(QD)

Part Number: BQ24196

Hi Experts,

Can you help to check what's the accuracy/tolerance for bq24196 charging current when REG02 Bit[0] set to 1? In our customer's application, they set REG02 to 0x7D. Normally the charging current should be ~500mA, but they found some chips current will be ~410mA. We tested the NG chips on our EVM, the phenomenon is the same as on customer's board. Please help to check it.

Thanks a lot!

    Hey Jackie,

    Please see below. We have not taken data for min/max or accuracy for this parameter during testing, apart from the point seen in the datasheet below. Understandably, this is not the same charge current setpoint your customer is using (104mA vs 500mA), but it may give a rough idea as to how far lower the current may be in actually, across devices. 

    Regards,
