Weltrend Announces Availability of the WT6639F Dual-port USB PD and Qualcomm QC Controller
|Hsinchu, Taiwan, November 16, 2020 – Weltrend Semiconductor (TWSE: 2436) today announced the release of the WT6639F dual-port USB Power Delivery (USB PD) and Qualcomm® Quick Charge controller.|
|The WT6639F is a highly integrated USB Power Delivery (USB PD) controller that supports USB PD 3.0 Programmable Power Supply specification and Qualcomm Quick ChargeTM 3+/4/4+/5 technologies. It is designed for USB Type-C® wall chargers and car chargers with multiple port solution. The multiple port solution offers a few design options, such as two USB Type-C ports (2C), two USB Type-C ports with two USB Std-A ports (2C2A), and etc.|
|The WT6639F minimizes external components by integrating two sets of USB PD baseband PHY, USB Type-C cable detection, Vconn power supply (for E-marked cable), voltage and current monitors, NMOS load switch driver and an 8-Bit MCU to allow small form factor and low BOM cost. Wide operation voltage range (3V to 24V) supports USB PD 3.0 Programmable Power Supply (PPS) specification.|
|The WT6639F is equipped with dual constant voltage (CV) and constant current (CC) features and can use I2C interface or FB pin to communicate with buck/boost controllers to control the output voltage and current of USB PD and fast charge adapters/chargers. A Multi-Time-Programmable (MTP) ROM is provided for program code and user configuration data and for any firmware update during development phase.|
|The WT6639F offers both USB Type-C and USB Std-A cable, UFP device, detection to customize the output power of USB Type-C port once a cable insertion event is detected, hence fulfills the power sharing capacity for multiple port chargers.|
