SMSC USB333x / USB334x USB 2.0 Transceivers

SMSC USB333x / USB334x USB 2.0 Transceivers

SMSC USB333x / USB334x Hi-Speed USB 2.0 transceivers deliver enhanced USB functionality for the portable market with support for the latest USB-IF Battery Charging 1.1 (BC 1.1) specification. This SMSC family of USB 2.0 devices provides three times the charging current through a USB port over traditional solutions. It also dramatically reduces system bill-of-material (BOM) costs over competitive solutions. The new USB333x / USB334x provides 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. USB333x / USB334x USB 2.0 transceivers come in small footprint packages that reduce the number of external components through the integration of voltage regulators and other discretes.
