WT6653P
The WT6653P is a highly integrated USB Power Delivery (USB PD) controller that supports USB PD 3.0 Programmable Power Supply (PPS) specification, Universal Fast Charging Specification for mobile devices (UFCS) and Qualcomm® Quick Charge ™ 4 or Quick Charge 4+ technologies. It is designed for USB Type-C® power source applications such as power adapters, wall chargers, car chargers, power strip, power bank, and etc. The WT6653P minimizes external components by integrating USB PD baseband PHY, UFCS 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 specification. One-Time-Programmable ROM is provided for program code and user configuration data.
