【 General Description 】

The WT6632F is a highly integrated USB Power Delivery (PD) controller that supports USB PD 3.0 specification designed for USB Type-C Downstream Facing Port (Source) charging applications such as travel adapters, charger, and power banks.

The WT6632F minimizes external components by integrating USB PD baseband PHY, 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.
