RT1711P
USB PD Port and Power Controller
General Description
The RT1711P is a USB Type-C and Power Delivery (PD)
controller, which complies with the latest USB Type-C
and PD standards. The RT1711P integrates a complete
Type-C transceiver including the Type-C termination
resistors, Rp and Rd, and enables the USB Type-C
detection including attach and orientation. It also integrates
the physical layer of the USB BMC power delivery protocol,
allowing power transfers of up to 100W and role swap.
The BMC PD function provides full support for Alternate
Modes on the USB Type-C standard. The RT1711P
provides a complete power management solution, which
consists of one barrel jack path and one VBUS path for
charging systems. Another provider path provides a
seamless voltage transition and avoids the discontinuity
of voltage transition during USB PD power contracts.
