3 Description
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) protocol.
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.
