3 Description
The TPS65986 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 TPS65986
communicates on the CC wire using the USB PD
protocol. When cable detection and USB PD
negotiation are complete, the TPS65986 enables the
appropriate power path and configures alternate
mode settings for (optional) external multiplexers.
The mixed-signal front end on the CC pins advertises
default (900 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 passes 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 TPS65986 is also an Upstream-Facing Port
(UFP), Downstream-Facing Port (DFP), or Dual-Role
Port for data. The port data termination passes data
to or from the top or bottom D+/D– signal pair to the
USB 2.0 Low Speed Endpoint. The power
management circuitry can utilizes a 3.3-V power
supply inside the system and also uses VBUS to start
up and negotiate power from a dead battery or no
battery condition.
