USB Type-C Configuration Channel Logic and Port Control

GENERAL DESCRIPTION The SGM7220 enables USB Type-C ports with the Configuration Channel (CC) logic needed for Type-C interface. The SGM7220 uses the CC pins to determine port attachment and detachment, cable orientation, role detection and port control for Type-C current mode. The SGM7220 ca

USB Type-C Configuration Channel Logic and Port Control

SGM7220 是一款支持 USB Type-C 端口的芯片，它内置了配置通道（CC）逻辑，这是 Type-C 接口所必需的。SGM7220 利用 CC 引脚来识别 Type-C 电流模式下的端口连接与断开、电缆方向、角色检测以及端口控制。SGM7220 能够被配置为下游端口（DFP）、上游端口（UFP）或双角色端口（DRP），这使得它成为大多数应用的理想选择。\nSGM7220 根据 Type-C 规范，可以交替配置为 DFP 或 UFP。CC 逻辑块监控 CC1 和 CC2 引脚上的上拉或下拉电阻，以确定 USB 端口何时连接、电缆方向以及检测到的角色。CC 逻辑会根据检测到的角色来识别 • 电源电压范围：2.7V 至 5V\n• 支持 USB Type-C 规范 1.1\n• 启用控制：低电平有效（EN 引脚）\n• 向后兼容 USB Type-C 规范 1.0\n• 支持高达 3A 的电流通告和检测\n• 模式配置• 仅主机 - DFP（源）\n• 仅设备 - UFP（接收器）\n• 双角色端口 - DRP\n• Try.SNK;
