1 Hardware Design Guideline for TPS65987DDH USB Power Delivery Controllers

TPS65987DDH is a third generation of USB Power Delivery Controllers from Texas Instruments. This device is compliant to USB Power Delivery Specification 3.1 and USB Type-C Specification 1.2.

This device integrates power FETs, various power management features, BC 1.2 host and device, 20 GPIOs, a Cortex M0 core and so forth. The integrated FETs inside the device supports up to 60 W of power per port. It includes all the necessary power management and protection circuitry such as reverse current protection (RCP), under voltage protection (UVP), over voltage protection (OVP) and so forth. Most of the GPIOs can be assigned to various events to control various parts of the system such as alternate mode multiplexers, DC-DC converters and so forth. A combination of all these features in a single chip provides a compelling solution for notebooks, docking stations and other space constrained applications.

This application note provides guidelines to design hardware using the TI PD Controller. This application note explains the features, pins, and signals of the device. It also shows how to maintain signal integrity for high speed signals.

For more information on applications and use cases, customers should refer to the data sheet and other application notes for this device.
