3 Description
The TPS65982 is a stand-alone USB Type-C &
Power Delivery (PD) controller providing cable plug
and orientation detection at the USB Type-C
connector. Upon cable detection, the TPS65982
communicates on the CC wire using the USB PD
protocol. When cable detection and USB PD
negotiation are 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 (500 mA), 1.5 A or 3 A for Type-C power
sources, detects a plug event and determines the
USB Type-C cable orientation, and autonomously
negotiates USB PD contracts by adhering to the
specified bi-phase marked coding (BMC) and
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 bi-directional 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 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 or Thunderbolt™, for
example).
The power management circuitry utilizes a 3.3 V
inside the system and also uses VBUS to start up
and negotiate power for a dead-battery or no-battery
condition.
