The TPS65982 device is a stand-alone USB Type-C and power delivery (PD) controller
providing cable-plug and orientation detection at the USB Type-C connector. Upon cable detection,
the TPS65982 device communicates on the CC wire using the USB PD protocol. After successful USB PD
negotiation is complete, the TPS65982 enables the appropriate power path and configures alternate
mode settings for internal and (optional) external multiplexers.
The mixed-signal front end on the CC pins advertises default, 1.5 A or 3 A for USB Type-C
power sources, detects a plug event and determines the Type-C cable orientation, and autonomously
negotiates USB PD contracts using bi-phase marked coding (BMC) and the physical layer (PHY)
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 TPS65982 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; additionally, the Sideband-Use (SBU) signal pair is used
for Alternate Modes. The power management circuitry supports dead battery or no-battery operation
using VBUS as a primary power supply when 3.3 V is not available.
For all available packages, see the orderable addendum at the
end of the data sheet.
