The TPS65983 B is a highly integrated stand-alone USB Type-C and Power Delivery (PD) controller optimized for notebook applications. The TPS65983 B integrates fully managed power paths with robust protection for a complete USB-C PD solution. The TPS65983 B includes a high speed multiplexer which is dependent the USB Type-C cable orientation that the CC pins provide. The multiplexer passes through side-band use data for alternate modes. The TPS65983 B has a BGA MicroStar Junior package with 0.5-mm Pitch and through-Hole via compatible for all pins.
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 B 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 uses 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.
