●Description
■The STUSB1602 is a generic IC designed in a 20V technology. It addresses USB Type-C™ port management both on the host and/or device side, and is suited for a broad range of applications.
■The STUSB1602 can handle all functions from Type-C attach detection, plug orientation detection, host to device connection, VCONN support, and VBUS configuration.
■It also provides a USB PD TX/RX line driver and BMC (biphase mark coding) transceiver which allows USB PD negotiation and alternative mode through an external MCU.
■Additionally, the STUSB1602 provides support for dead battery operation.
●Functional description
■The STUSB1602 is a USB Type-C controller IC. It is designed to interface with the Type-C receptacle both on host and/or device sides. It is used to establish and manage the source-to-sink connection between two USB Type-C host and device ports.
▲The major role of the STUSB1602 is to:
◆Detect the connection between two USB Type-C ports (attach detection)
◆Establish a valid source-to-sink connection
◆ Determine the attached device mode: source, sink or accessory
◆ Resolve cable orientation and twist connections to establish USB data routing (mux control).
◆ Configure and monitor the VBUS powerpath
◆Manage VBUS power capability: USB default, Type-C medium or Type-C high current mode.
◆ Configure VCONN when required8. Support USB PD negotiation
▲The STUSB1602 also provides:
◆.Low power standby mode
◆ Dead battery mode
◆. I²C interface and interrupt
◆ Start-up configuration customization: static through NVM and/or dynamic through I²C
◆ High voltage protection6. Accessory mode detection
