Description
AI
The TPS65981 is a highly integrated stand-alone USB Type-C and Power Delivery (PD) controller optimized for notebook applications. The TPS65981 integrates fully managed power paths with robust protection for a complete USB-C PD solution. The TPS65981 integrates 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 TPS65981 has a QFN package for reliable manufacturing with 0.5-mm Pitch and 2-Layer PCB compatibility and has an extended (industrial) temperature range. The TPS65981 is USB PD 2.0 certified which is no longer certifiable through USB IF.
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 TPS65981 device 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, for example).
The power-management circuitry uses 3.3 V inside the system and also uses VBUS to start up and negotiate power for a dead-battery or no-battery condition.
