9.2.1 Design Requirements
9.2.1.1 Programmable Power Supply (PPS) - Design Requirements
Programmable Power Supply (PPS) defines a specific voltage and current (Augmented Power Data Object)
that is used in direct charging applications. A PPS source needs to meet the source voltage and current
resolution required for direct charging applications. A PPS sink requests the voltage and current required for
direct charging within the capabilities of PPS source.

9.2.1.2 Liquid Detection Design Requirements
Portable Type-C and PD applications are subject to environments that wet the Type-C connector. Liquid on
the Type-C connector leads to corrosion or system damage. Detecting liquid leverages the SBU1/2 pins on the
Type-C connector to not interfere with USB2/3 operation or PD communication.
