4.5 USB PORT(S)

General parameters such as current limit delay, VBUS undervoltage protection, programmable power supply enable or disable, and USB legacy fast charge mode enable or disable are configurable in this page.

TPS25763-Q1 can be configured as Dual Role Power (DRP) or Source Only. DRP ensures the port can connect to source-only peripherals. If TPS25763D-Q1 is DRP and connects as sink, a 5V, 0A contract will be requested and the system should not sink significant current. DRP also ensures compliance to the DisplayPort™ over USB-C™ specification. Source Only implementation simplifies the hardware design and should be acceptable in the majority of applications.

Some USB peripherals require to be in the Downstream Facing Port (DFP) role to operate. TPS25763-Q1 can be configured to initiate a role swap to Upstream Facing Port (UFP) or handle this request when given from the port partner.
