Functional description

The STUSB1600 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 STUSB1600 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 power path

Manage VBUS power capability: USB default, Type-C medium or Type-C high current

mode.

Configure VCONN when required

The STUSB1600 also provides:

Low power standby mode

Dead battery mode

I2C interface and interrupt (optional connection to the MCU)

Start-up configuration customization: static through NVM and/or dynamic through I2C

High voltage protection

Accessory mode detection
