描述 Description

The WT6631P is a highly integrated USB Power Delivery (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, 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 PD 3.0 specification. One-Time-Programmable ROM is provided for program code and user configuration data.
