Description
The STUSB1702 is a generic IC, in a 20 V technology it addresses a USB Type-C™
port management on the host side. It 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.
It also provides a USB PD TX/RX line driver and BMC (bi-phase mark coding)
transceiver which allow USB PD negotiation and an alternate mode through an
external MCU.

Applications
• Car charger, car infotainment
• Smart plugs, wall adapters, and chargers
• Power hubs and docking stations
• Any Type-C source device
