It is designed to interface with the Type-C receptacle on host side. It is used to establish and manage the source-to-sink connection between two USB Type-C host and device ports. The STUSB1602 major role is to: 1. Detect the connection between two USB Type-C ports (attach detection) 2. Establish a valid source-to-sink connection 3. Determine the attached device mode: source, sink or accessory 4. Resolve cable orientation and twist connections to establish USB data routing (MUX control) 5. Configure and monitor V power path BUS 6. Manage V power capability: USB default, Type-C medium or Type-C high current mode BUS 7. Configure V when required CONN 8. Support USB PD negotiation The STUSB1602 also provides: Dead battery mode IC interface and interrupt Start-up configuration customization: static through NVM and/or dynamic through IC High voltage protection Accessory mode detection Figure 1.
