WT6678F
The WT6678F is a highly integrated USB Power Delivery (USB PD) controller that supports USB PD 3.1 SPR & EPR 48V specification. It is designed for USB Type-C® power source applications such as power adapters, wall chargers, car chargers, power strip.The WT6678F minimizes external components by integrating USB PD baseband PHY, USB Type-C detection, shunt regulator, 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 (3.3V to 56V) supports USB PD 3.1 SPR & EPR 48V specification. A Multi-Time-Programmable (MTP) ROM is provided for program code and user configuration data.
