AP43776Q Typical Applications Circuit
(continued)
Application 3: Alternate Mode and BC 1.2 CDP Mode Support
The AP43776Q not only supports power protocol decoding, but also provides data link capability. Figure 4 illustrates an AP43776Q application scenario of power source and data link. One of the ports is used as a Type-C connector, which is connected to the Notebook host or smart phone device. The power from Down Facing Port (DFP) is sourced out to the Notebook/device, and the video data from Up Facing Port (UFP) is linked to the car navigation system through the AP43776Q supporting alternative mode. During the handshake, the AP43776Q decodes the alternative mode information of the Notebook host’s or device’s CC commands, and then the information is sent to the high-speed mux to switch the data path accordingly. The other ports may be used as a Type-A connector supporting BC 1.2 CDP mode, where not only power is sourced out for the device, but also data may be linked to the car navigator at the same time.
