WT6633P数据手册Weltrend中文资料规格书

描述 Description

The WT6633P is a highly integrated USB Power Delivery (PD) controller that supports USB PD 3.0 Programmable Power Supply specification and Qualcomm® Quick ChargeTM 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 WT6633P 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 (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.
