Star Xu：

您好，正在查询，稍后回复。

andrew zhi：

好，问题比较紧急，请帮忙加急一下，感谢

andrew zhi：

Gauge是外挂的三方芯片，电流是gauge i2c读的bat adc的采样数据为700mA

Star Xu：

您好，看到E2E已经回复您的帖子，请继续关注。

andrew zhi：

我看Jame反馈，需要直接沟通，是通过什么方式沟通？

,

Star Xu：

您好，方便提供下面的信息吗？

Customer Name

Device

Total Amt (Ku)

Project Name / ID

Competition Device

End Equipment

Production Start Date

andrew zhi：

Hi Star,

     这些属于客户敏感信息，不方便提供，请知，感谢

BRs,

Andrew

Star Xu：

您好，请确认

1. VBUS (voltage at VBUS pin), IVBUS, VBAT (voltage at BAT pin), IBAT, VSYS, ISYS的运行条件

2，充电器操作异常时的所有寄存器读数（不是长时间的寄存器存储）。寄存器读数有助于了解充电运行状态和故障条件。

下面文档应该对您有帮助。

Hi Star，

  上面附的log，就是刚出现问题后立即dump出来的，不太明白你说的（不是长时间的寄存器存储）这个如何理解？

Star Xu：

您好，为了研究具体案例，当认为两个充电器的充电器操作异常时，都需要上面的两点信息，

您已经提供了register信息，是否方便提供 VBUS (voltage at VBUS pin), IVBUS, VBAT (voltage at BAT pin), IBAT, VSYS, ISYS的运行条件

andrew zhi：

Hi Star，

     波形暂时没法提供，本地正在抓，由于抓波形的机器不一定能复现所以可能比较久

,

Star Xu：

您好，好的，了解
