RT1716
Programmable USB Type-C PD Controller
General Description
The RT1716 is a USB Type-C controller that complies
with the latest USB Type-C and PD standards. The RT1716
integrates a complete Type-C Transceiver including the
Rp and Rd resistors. It does the USB Type-C detection
including attach and orientation. The RT1716 integrates
the physical layer of the USB BMC power delivery protocol
to allow up to 100W of power and role swap. The BMC PD
block enables full support for alternative interfaces of the
Type-C specification.
