Description

The TPS65983 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 TPS65983 communicates on the CC wire using the USB PD protocol. When cable detection and USB PD negotiation are complete, the TPS65983 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 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 TPS65983 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.
