TWO-PORT, THREE-PORT, AND FOUR-PORT SOURCE-ONLY APPLICATIONS

(E.G., AUTOMOTIVE REAR SEAT CHARGING) (UPD301B ONLY)

Some applications, such as a automotive rear seat charging port, may need multiple USB Type-C™ power delivery

ports. These ports can be implemented by connecting a UPD301B and a UPD350 via the SPI interface, as shown in

Figure 2-2. The UPD301B will execute the stack for the UPD350. The two-port implementation supports dynamic power

allocation (e.g., go-to power min based on an external input).
