WT6635P数据手册Weltrend中文资料规格书

描述 Description

The WT6635P is a highly integrated USB Power Delivery (PD) controller that supports USB PD 3.0 Programmable Power Supply specification and QualcommR Quick ChargeTM 4 or Quick Charge 4+ technologies. It is designed for USB Type-C power source applications such as power adapters, wall chargers, power strip, and etc.
The WT6635P minimizes external components by integrating USB PD baseband PHY, Type-C detection and an 8-bit MCU to allow small form factor and low BOM cost. Low operation voltage (3V) supports PD 3.0 Programmable Power Supply (PPS) specification. One-Time-Programmable ROM is provided for program code and user configuration data.
Without the features of Constant Voltage (CV), Constant Current (CC), voltage/current monitoring and load switch control pin, WT6635P must pair with the CV/CC controller, equipped with dynamic Over Voltage/Current Protection (OVP/OCP) & load switch control pin, by I2C interface.
