Summary

The USB3343 family of Hi-Speed USB 2.0 transceivers delivers enhanced USB functionality for the portable market with support for the latest USB-IF Battery Charging 1.1 (BC 1.1) specification. This family of devices dramatically reduces the time required for battery charging and system bill-of-materials (BOM) costs by up to 60% over competitive solutions. The new USB3343 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. The USB3343 is designed in a small footprint package and reduces the number of external components through the integration of voltage regulators.
