FM XPD736B20

XPD736 is a versatile USB Type-C and Type-A dual-port controller integrating USB Type-C, USB Power Delivery (PD) 2.0/3.0 with PPS, QC3.0/2.0 CLASS A fast charging protocols, Huawei FCP/SCP fast charging protocols, Samsung AFC fast charging protocol, BC1.2 DCP, and Apple device 2.4A charging specification. The built-in Type-C protocol of XPD736 supports automatic wake-up upon Type-C device insertion, intelligent detection of plug orientation (front and reverse insertion), and seamless connection establishment. The integrated PD protocol supports Biphase Mark Coding (BMC) with a hardware-implemented physical layer protocol and protocol engine, requiring no software involvement in encoding/decoding. When either the Type-C or Type-A port has a device connected, each port can deliver independent fast charging. When both Type-C and Type-A ports are connected simultaneously, XPD736 reduces the output voltage to 5V to power both devices. Notably, when a charging cable remains connected to the Type-A port without an Apple device attached, the Type-C port retains full fast charging capability. In charger applications where charging cables are frequently kept connected, XPD736 effectively resolves the fast charging challenge when both Type-A and Type-C ports are used with permanently attached cables. In addition, the Type-A port full-charge cutoff current threshold is as low as 10mA, supporting low-current charging for smart wearable devices. XPD736 achieves dynamic voltage regulation by connecting a single Sink/Source current source to the feedback pin of an AC-DC or DC-DC converter. Both startup and voltage adjustment processes feature soft-start functionality, ensuring smooth voltage transitions. XPD736 incorporates multiple built-in protection mechanisms to ensure device safety, including dynamic overvoltage/undervoltage/overcurrent protection (protection thresholds are proportionally adjusted based on the device-requested operating voltage/current) and startup monitoring (port voltage is checked for safe conditions before VBUS output is enabled). XPD736 integrates a 20mΩ VBUS path power switch with built-in dual discharge paths for VPWR and VBUS, reducing external component count while enabling rapid output shutdown and recovery to a safe state upon fault detection. XPD736 is offered in a TSSOP16 package with a minimal external component count, facilitating straightforward USB PD certification testing.
