Part Number: BQ25713 Other Parts Discussed in Thread: EV2400 ,
使用EV2400读取到寄存器状态如上面图片所示。实际工况为:VBUS正常供电,且在有效范围内;电池为2S模式,且连接上电池,实测VSYS也有电压;
BQ25713的开关电路也一直不工作,是否是因为对于VBUS和VSYS的测量出现问题造成的,或是其它原因。
请专家给予指导解惑。

您好, This problem could be related to the auto wakeup feature. This is controlled by the AUTO_WAKEUP_EN bit. Try putting the charger into HiZ mode, disabling the AUTO_WAKEUP_EN bit, then enabling charge.
