什么是 E-Marker 芯片？
USB-C 充电线连接器上有一个名为 E-Marker（电子标记线缆）的芯片，类似于充电线的安全 ID 卡。这实际上是一种协议控制器功能，用于监控充电状态并帮助合理分配电流。
目前，市场上大多数 USB-C 充电线的规格为 3A 和 5A。根据 USB-IF 协会的规定，如果电源适配器的电流输出超过 3A（100W）或 5A（240W），则必须集成 E-Marker 芯片，以确保在安全保护机制下进行充电。下表根据各种参数对这些 E-Marker 电缆进行了区分。

What is the E-Marker chip?
The USB-C charging cable connector has a chip called an E-Marker (Electronic Marked Cable), similar to the charging cable’s security ID card. This is actually a protocol controller feature that monitors the charging status and helps to properly allocate the current.
Most USB-C charging cables on the market today have specifications of 3A and 5A. According to USB-IF Association regulations, if the current output of the power adapter exceeds 3A (100W) or 5A (240W), an E-Marker chip must be incorporated to ensure that charging occurs under a safety protection mechanism. The following table distinguishes these E-Marker cables according to various parameters
