WT6633P

【 General Description 】

The WT6633P 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, 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.

The WT6633P is verified by GRL for Qualcomm Quick Charge 4. Read the cover page of GRL Compliance Test Report for WT6633P.

The WT6633P is also verified by UL for Qualcomm Quick Charge 4+ if Quick Charge 3.0 and Quick Charge 2.0 backward compatibilities are desired. Read the UL Verification Certificate for WT6633P.
