USB Power and Charging Port Controllers
WT6673F
| 【 General Description 】 |
| The WT6673F is a highly integrated USB Power Delivery (USB PD) Dual Role Port (DRP) controller that supports USB PD 3.0 Programmable Power Supply specification and Qualcomm® Quick ChargeTM 4, Quick Charge 4+, and Quick Charge 5 technologies. It is designed for USB Type-C® power source applications such as power adapters, wall chargers, car chargers, power strips, power banks, and etc. |
| The WT6673F minimizes external components by integrating USB PD baseband PHY, USB Type-C detection, shunt regulator, voltage and current monitors, NMOS and PMOS 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 product consists of a 32K x 8 flash memory for program code and user configuration data. The large memory capacity allows flexibility in multi-protocol supports and authentication functions when needed. |
