WT6632F

The WT6632F is a highly integrated USB Power Delivery (USB PD) controller that supports USB PD 3.0 specification and Qualcomm^® Quick Charge ™ 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).
