Overview
The TPS65981ABIRTQR is a highly integrated USB Type-C and USB Power Delivery (PD) controller developed by Texas Instruments. This device is optimized for various applications, including notebook and other personal electronics, and is known for its robust power management and high-speed data multiplexing capabilities. The TPS65981 integrates fully managed power paths with comprehensive protection features, making it a complete solution for USB-C PD implementations. Although it is certified for USB PD 2.0, it is important to note that new designs should use a PD3.0 compliant device as PD2.0 certification is no longer available as of June 2020.
