数据： 每载波多通道(MCPC) 兼容USB 端口多媒体开关支持USB，通用异步收发器(UART)，音频，ID，麦克风(MIC) 和负载开关 数据表
TSU6721是特有自动开关和附件检测的高性能USB端口接多一个普通USB端口以传送音频，USB数据，充电，如影随形（OTG）和工厂模式信号。具有负信号功能的音频路径包括左（单声道/立体声），右（立体声）以及麦克风信号。此外，TSU6721与MCPC技术规格兼容。
TSU6721特有阻抗检测功能，这个附件通过USB连接器的DP，DM和ID引脚连接。此开关由自动开关或通过I 2 C进行手动控制。
TSU6721具有一个集成型低电阻负载开关，此开关用来将充电器与外部连接器隔离开。过压保护和可编程过流限制器/保护功能是负载开关所包含的额外特性。
充电器检测符合USB充电器技术规格v1.2。除了DCP，CDP和SDP，此器件还能够检测苹果（Apple）充电器。
当连接，这个器件由系统的VBAT或通过VBUS供电。当在开发和制造中使用USB /UART JIG线缆时，TSU6721支持工厂模式测试。
