WT6616F
The WT6616F is a highly integrated USB Power Delivery (USB PD) Dual Role Port (DRP) controller that supports USB PD 3.0 Programmable Power Supply specification. It is designed for device that supports dual-role USB PD functions such as power banks. The WT6616F 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 (3V to 24V) supports USB PD 3.0 Programmable Power Supply (PPS) specification. A Multi-Time-Programmable (MTP) ROM is provided for program code and user configuration data. The WT6616F is certified by USB Implementers Forum (USB-IF) for USB Type-C PD (TID: 2169).
