XPD319B

XPD319 is a multi-protocol port controller integrating USB Type-C, USB Power Delivery (PD3.0) with PPS, QC3.0+/QC3.0/QC2.0 fast charging protocols, Huawei FCP, Samsung AFC, BC1.2 DCP, and Apple 2.4A charging specification, providing a cost-effective USB Type-C port charging solution for AC-DC adapters, car chargers, and similar applications. The built-in Type-C protocol supports automatic wake-up upon device insertion, intelligent detection of plug orientation (forward/reverse), and seamless connection establishment. The integrated PD protocol supports Biphase Mark Coding (BMC) with a hardware-implemented physical layer and protocol engine, requiring no software involvement in encoding/decoding. XPD319 supports up to 36W output power. Broadcast PDO voltages are configurable as 5V/9V/12V, with two APDO voltage ranges configurable: 5V Prog and 9V Prog. XPD319 achieves dynamic voltage regulation via a single Sink/Source current source connected to the feedback pin of an AC-DC or DC-DC converter. XPD319 features VDD undervoltage protection, VBUS overvoltage protection, and overvoltage protection on DP/DM and CC1/CC2. XPD319 is available in an SOP8 package.
