USB Power and Charging Port Controllers
WT6635P
| 【 General Description 】 |
| The WT6635P is a highly integrated USB Power Delivery (PD) controller that supports USB PD 3.0 Programmable Power Supply specification. 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 a controller with CV/CC functions, such as Power Integrations’ InnoSwitch3-Pro, equipped with dynamic Over Voltage/Current Protection (OVP/OCP) and load switch control pin, controlled by the WT6635P via I2C interface. |
| The WT6635P is verified by GRL for Qualcomm® Quick ChargeTM 4+. Read the Qualcomm Quick Charge 4+ Technology certification and the cover page of GRL Compliance Test Report for WT6635P. |
