USB Power and Charging Port Controllers
WT6633P
【 General Description 】 |
The WT6633P is a highly integrated USB Power Delivery (USB PD) controller that supports USB PD 3.0 Programmable Power Supply specification, Qualcomm® Quick ChargeTM 4, Quick Charge 4+, and Quick Charge 5 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 WT6633P minimizes external components by integrating USB PD baseband PHY, USB Type-C detection, shunt regulator, voltage and current monitors, NMOS or PMOS 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 PD 3.0 Programmable Power Supply (PPS) specification. One-Time-Programmable ROM is provided for program code and user configuration data. |
The WT6633P is certified by USB Implementers Forum (USB-IF) for USB Type-C PD (TID: 1070018) and by UL for Qualcomm Quick Charge 4+ (Certificate Number: 4788566324-2) and Qualcomm Quick Charge 5 (Certificate Number: 4789627043-2). |
