WT6631P

The WT6631P is a highly integrated USB Power Delivery (USB PD) controller that supports USB PD 3.0 specification. It is designed for USB Type-C® power source applications such as power adapters, wall chargers, car chargers, power banks, and etc. The WT6631P 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. The WT6631P supports 5V to 20V USB PD 3.0 specification. One-Time-Programmable ROM is provided for program code and user configuration data. The WT6631P is certified by USB Implementers Forum (USB-IF) for USB Type-C PD (TID: 1090014).
