WT6655P
The WT6655P is a highly integrated USB Power Delivery (PD) controller that supports USB PD3.2 SPR PPS (Programmable Power Supply) and AVS (Adjustable Voltage Supply). It is designed for USB Type-C power source applications such as power adapters, wall chargers, car chargers, power strip and power bank. The WT6655P 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. Wide operation voltage range (4V to 24V) supports PD3.2 Programmable Power Supply (PPS) specification. One-Time-Programmable ROM is provided for program code and user configuration data.
