USB333x & USB334x USB 2.0 Transceivers

Microchip Technology USB333x and USB334x USB 2.0 Transceivers deliver enhanced USB functionality for the portable market with support for the USB-IF Battery Charging 1.2 (BC 1.2) specification. These devices provide an excellent compliment to USB charging ports by enabling portable devices to negotiate up to three times the charging current compared to a standard USB port, resulting in faster battery charging. The USB333x and USB334x Transceivers are offered in small footprint packages and reduce the number of external components through the integration of voltage regulators and other discretes. Additionally, Microchip offers a complementary and confidential USBCheck™ online design review service for customers who select the USB333x or USB334x for their application design-in.
