The STUSB1700 is an IC controller, fully compliant with the USB Type-C cable and connector specification (rev. 1.2), which addresses 5 V USB Type-C port management on the host side. It is fully autonomous and allows the advertising of the current capability to be managed by external pins. It is suited to implement power sharing capabilities, or external temperature protection mechanism with current capability adjustment.
The STUSB1700 is designed for a broad range of applications and can handle the following USB Type-C functions: attach detection, plug orientation detection, host to device connection, VCONN support, and VBUS configuration. Thanks to its 20 V technology, it implements high voltage protection features against short-circuits to VBUS up to 28 V. The device is fully customizable thanks to an integrated non-volatile memory.
