USB Power and Charging Port Controllers
WT6675P
【 General Description 】 |
The WT6675P is a highly integrated USB Power Delivery (USB PD) controller that supports USB PD 3.1 SPR & EPR 36V specification. It is designed for USB Type-C power source applications such as power adapters, wall chargers, car chargers, and power strip. |
The WT6675P 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 3.1 SPR & EPR 36V specification. One-Time-Programmable ROM is provided for program code and user configuration data. |
The WT6675P is certified by USB Implementers Forum (USB-IF) for USB PD 3.1 140W (TID: 9066). |
