3 描述

TPS65982DMC 是一种坞站管理控制器，用于实现 TI PD 控制器的坞站、集线器和监视器。TPS65982DMC 包括一个 USB 低速端点，能够接收系统 PD 控制器的固件更新。固件更新使用 SHA-256 和 RSA-3072 身份验证安全地执行。此外，端点还提供 USB 广告牌功能。TPS65982 DMC 集成了背对背 NFET 驱动器，用于通过外部适配器控制系统电源。DMC 监控通过适配器输入路径以及系统其他点的电流，并调整受管 PD 控制器的功率通告，以确保外部适配器不会过载。当包含在 USB4 系统中时，TPS65982DMC 会监控上行端口的连接状态并更新下行端口的连接状态，以确保整个系统的数据行为一致。
