[参考译文] BQ25713：检测电池移除

您好 Justin、

为了检测电池是否移除、请测量电池充电电流。 ENABLE、ADC_ICHG 和 ADC_START 之后、通过读取寄存器0x28测量充电电流。 电池移除后、它将显示充电电流为零。 当读取电流时、请确保寄存器0x02中的充电电流限制设置为高于零电流的值。

您好、Munir、

感谢您的反馈。

我们已经尝试过这种方法、它没有帮助。

实际上、我们的系统始终通过 USB 连接并使用 VBUS 电源运行。 仅在浪涌情况下、电源从电池中提取(500 mA

由于系统在500mA 内运行、完全由 USB 供电且电池已充满电、因此没有充电/放电电流。
因此、无论是否连接电池、寄存器0x28和0x29都为0。

存在蓄电池
