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
