BQ24195用iPad官方2.1A充电器时充电,REG08[7:7]显示为00(无输入或DPDM检测未完成)



请问如何解决这个问题?

将REG07[7]写为1后,然后读出还是0

  • datashee内容t如下:00 – Unknown (no input, or DPDM detection incomplete), 01 – USB host, 10 – Adapter
    port, 11 – OTG

    apple的适配器不属于BC1.2,为非标适配器,所以B24195识别为unknown 适配器。这是正常的,不是问题。

    此时的默认current limit比较小,建议你用I2C去改写成一个更好的值。
