RT1715
Programmable USB Type-C PD Controller
General Description
The RT1715 is a USB Type-C controller that complies
with the latest USB Type-C and PD standards. The RT1715
integrates a complete Type-C Transceiver including the
Rp and Rd resistors. It does the USB Type-C detection
including attach and orientation. The RT1715 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.

Pin Function
Type-C Connector Configuration Channel (CC) pins. Initially used to determine
when an attach has occurred and what the orientation detected.
VBUS input pin for attach and detach detection when operating as an UFP port
(Device).
Input supply voltage.
Regulated input pin to be switched to correct CC pin as VCONN to power
Type-C full-featured cables and other accessories.
Active low and open drain type interrupt output used to prompt the processor to
read the registers.
