TUSB321器件可在USB Type-C端口上实现Type-C生态系统所需的配置通道(CC)逻辑.TUSB321器件使用CC引脚来确定端口的连接状态和电缆方向,以及进行角色检测和C型电流模式控制。TUSB321器件可配置为下行端口(DFP),上行端口(UFP)或双角色端口(DRP),因此成为任何应用的理想选择。
根据C型规范,TUSB321器件配置为DRP时,会交替配置为DFP或UFP。CC逻辑块通过监视CC1和CC2引脚上的上拉或下拉电阻,以确定何时连接了USB端口,电缆的方向以及检测到的角色。CC逻辑根据检测到的角色来确定C型电流模式为默认,中等还是高。该逻辑通过实施V <子> BUS 子>检测来确定端口在UFP和DRP模式下是否连接成功。
该器件能够在宽电源范围内工作,并且具有较低功耗。TUSB321器件适用于工业级和商业级温度范围。
