9.2.1.3 BC1.2 Application Design Requirements

The PD controller taps the USB D+ and D- pins to provide BC1.2 detection and advertisement. The USB D+ and

D- are connected to the USB Host (DFP) or USB Device (UFP) from the Type-C connector for Charging Data

Port applications.

9.2.1.4 USB Data Support Design Requirements

For USB3 operation, the SSTX/RX are muxed to the Type-C connector. A SuperSpeed Mux generally has two

control signals; enable and plug orientation. The PD controller determines when a connection is detected and

drives the required GPIO to control the SuperSpeed Mux.

9.2.2 Detailed Design Procedure

9.2.2.1 Programmable Power Supply (PPS)

The TPS25751 supports Programmable Power Supply (PPS) source and sink. When the TPS25751 negotiates

a PPS contract as a source, the device enables the high-voltage power path (PPHV for D variant, PPEXT

for S variant) and communicate with the supported TI battery charger (BQ25792 and BQ25756) to supply the

negotiated voltage. TPS25751 only supports PPS within a 5V to 21V range according to PD 3.1 specification

and is enabled through the Application Customization Tool.
