5 Description (continued)

The port-power switch provides up to 3 A downstream at 5 V for legacy and Type-C USB power. An additional

bidirectional switch path provides USB PD power up to 3 A at a maximum of 20 V as either a source (host), sink

(device), or source-sink.

The TPS65981 device is also an upstream-facing port (UFP), downstream-facing port (DFP), or dual-role port for

data. The port-data multiplexer passes data to or from the top or bottom D+/D– signal pair at the port for USB 2.0

HS and has a USB 2.0 low-speed endpoint. Additionally, the sideband-use (SBU) signal pair is used for auxiliary

or alternate modes of communication (DisplayPort, for example).

The power-management circuitry uses 3.3 V inside the system and also uses VBUS to start up and negotiate

power for a dead-battery or no-battery condition.
