  电路保护:在USB端口的现实使用环境中,USB电路需要防范一系列电气事件。其中,最常见的就是静电放电(ESD)。例如,乘客在塑料椅子上来回挪动或摩擦地毯就会累积静电电荷。如果他们触碰暴露在外的USB端口,就可能破坏车内精密的电子设备,这些设备维修难度大,维修成本高。

  高压栅级驱动配资炒股杠杆经验:为了支持后向兼容,USB Type-C接口的默认电压为5V。在供电电压确定后,控制器可能需要从5V FET切换到20V FET,以支持更高功率的供电。如果该功能未集成在控制器中,则需要外加电路来驱动更大功率的FET,以便为Vbus提供20V电压。

  线缆补偿配资炒股杠杆经验:为方便起见,USB端口可能布局在车内各处,比如中控台、后座间的中央储物盒和/或杂物箱内。对于不单用于供电的USB端口(如数据功能),USB控制器还很有可能用于股票配资 娱乐系统。将储物盒中的端口连接到股票配资 娱乐系统可能需要长达10英尺的USB线缆。使用如此长的线缆可能造成严重的压降,对信号质量和可靠性造成不利影响。

  过温功率控制:采用USB Type-C的另一挑战是如何解决高达100W功率充电时产生大量热的问题。过热可能造成一系列问题,包括引发火灾和/或损坏正在充电的设备。临近的、对热比较敏感的组件,如股票配资 娱乐系统或导航系统的电子设备,也可能受到不利影响。过大的热耗散甚至可能破坏USB端口本身,需要昂贵的维护或保修。

  支持传统的USB Type-A口:虽然新设备将采用USB Type-C接口,但是使用USB Type-A接口的设备仍有数十亿之多。汽车OEM厂商需要提供Type-A端口,为这些传统设备提供支持。不必设计两个单独的USB子系统,现有的控制器能同时支持Type-A端口和Type-C端口(参见图3)。这类一体化控制器在简化系统设计的同时,最大限度地降低了总BOM成本。
