USB Power and Charging Port Controllers
WT6632F
【 General Description 】 |
The WT6632F is a highly integrated USB Power Delivery (USB PD) controller that supports USB PD 3.0 specification and Qualcomm® Quick ChargeTM 3.0 technology designed for USB Type-C® Downstream Facing Port (Source) charging applications such as power adapters, wall chargers, car chargers, power strip, power banks, and etc. |
The WT6632F minimizes external components by integrating USB PD baseband PHY, USB Type-C detection, shunt regulator, voltage and current monitors, and control circuits of blocking MOSFET, and an 8-bit MCU to allow small form factor and low BOM cost. It supports wide operation voltage range from 3V to 30V without the need of an external LDO. A Multi-Time-Programmable (MTP) ROM is provided for program code and user configuration data. |
The WT6632F is certified by USB Implementers Forum (USB-IF) for USB Type-C PD (TID: 1070017). |
