WT6640P
The WT6640P 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, and car chargers. The WT6640P minimizes external components by integrating USB PD baseband PHY, USB Type-C detection, shunt regulator, voltage and current monitors, 30V NMOS load switch and capless LDO to allow small form factor and low BOM cost. The WT6640P supports 5V to 20V USB PD 3.0 specification.
