【文字介绍】The TPS65982 is a stand-alone USB Type-C & 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 Power Delivery (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 1.5 A or 3 A for Type-C power providers, 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 can pass up to 3 A downstream at 5 V for legacy and Type-C USB power. An additional bidirectional switch path can provide USB PD power up to 3 A at a maximum of 20 V as either a provider (host), consumer (device), or provider-consumer.
The TPS65982 can also be a Downstream-Facing Port (DFP), Upstream-Facing Port (UFP), or Dual-Role Port (DRP) for data. The port data multiplexer can pass data to or from the top or bottom D+/D- signal pair at the port for USB 2.0 HS or UART 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 vendor-defined modes, for example).
The power management circuitry can utilize a 3.3-V or 5-V power supply inside the system, and also use VBUS to start up and negotiate power for a dead battery or no battery condition.
