WT6676F
The WT6676F is a highly integrated USB Power Delivery (USB PD) controller that supports USB PD 3.2 SPR & EPR 36V specification. It is designed for USB Type-C®power source applications such as power adapters, wall chargers, car chargers, and power strips. The WT6676F 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 45V) supports USB PD 3.2 SPR & EPR 36V specification. A Multi-Time-Programmable (MTP) ROM is provided for program code and user configuration data. The WT6676F is certified by USB Implementers Forum (USB-IF) for USB PD 3.1 140W (TID: 9065).
