VP222 - USB-C™ DFP CC Controller with Universal Battery Charging


The VIA Lab’s VP222 is an USB Type-C DFP CC controller which supports universal battery charging with an integrated USB 2.0 high-speed data switch. The VP222 provides the electrical measurement to support Type-C CC controller features. The VP222 also provides the backward compatibility with the electrical protocol handshake on D+/D- to support the battery charging schemes; BC 1.2, Chinese Telecommunication Standard YD/T 1591-2009, Divider Mode (complaint with Apple® devices), and DCP 1.2V Mode (compliant with Samsung devices).

The VIA Lab’s VP222 supports low/full speed HID (human interface device like mouse/keyboard) wake function. The wide bandwidth (1.2GHz) data switch features low capacitance and low on resistance, allowing signals to pass with minimum edge and phase distortion.
